A formula will return an error when Smartsheet expects different elements from the formula than what are provided. Below is a list of formula error messages, their causes, and the resolutions you can implement to fix the errors.

### #BLOCKED

#### Cause

The calculation is blocked because at least one of the cells referenced by the formula has an error.

#### Resolution

Determine which cell referenced by this formula contains an error, which will be more descriptive of the problem.

### #BOOLEAN EXPECTED

#### Cause

The formula is in a specific type of column (Date, Number, Symbol) and the returned value is of a different type.

#### Resolution

Either move the formula to a different column, or convert the result to the appropriate type. Formula results may be converted to text values by adding an empty string. For example =TODAY() + "" will allow you to enter today's date into a text column.

### #CALCULATING

#### Causes

The formula engine is still calculating on the backend.

- This can often mean you are experiencing a slowness error due to network conditions or heavy browser usage.
- It could also indicate that you are using a larger formula and/or the formula is referencing a cell that is referencing another cell via a formula or cell linking.

#### Resolution

Often this error corrects itself once the calculation is complete.

If the error doesn’t correct itself, slowness on a sheet can be influenced by several different factors. Some of the main factors:

**Browser speed**—browser speed can be one of the main contributors of slowness when loading, navigating, and saving a sheet. In our tests, we have found Smartsheet to perform best using Google Chrome. If it is an option or when troubleshooting, try using this browser to see if it improves your response times.**Advanced functionality**—widespread use of formulas, cell-linking, and conditional formatting can contribute to slower load times. If your sheet starts to slow down, try disabling conditional formatting rules to see if this is contributing to the issue. Also, consider getting rid of formula columns or cell-links which might no longer be needed.**Sheet size**—as sheets get larger, performance may decrease. When appropriate, move rows (more on Moving Rows) to an archival sheet.

If you are utilizing cross-sheet references you may wish to also confirm the sheet isn’t approaching the 100,000 cell reference limit.

### #CIRCULAR REFERENCE

#### Cause

The formula references itself. The circular reference may be direct where the reference is in the formula text itself, or indirect where this formula references a cell which then references back to this cell.

#### Resolution

Determine which reference is circular. Indirect references can be many levels deep. Sometimes it is easiest to make a copy of the formula and remove cell references until the error is eliminated. This process of elimination will help you see which reference is ultimately circular.

### #CONTACT EXPECTED

#### Cause

A formula in a Contact List field has returned a datatype other than text or contacts.

#### Resolution

Formulas in Contact List fields may only return text or contact datatypes. Adjust the formula to return one of those datatypes or move the formula into another type of field (Text/Number, Date, Dropdown List, Checkbox, or Symbol)

### #DATE EXPECTED

#### Cause

The formula is in a specific type of column (Date, Number, Symbol) and the returned value is of a different type.

#### Resolution

Either move the formula to a different column, or convert the result to the appropriate type. Formula results may be converted to text values by adding an empty string. For example =TODAY() + "" will allow you to enter today's date into a text column.

### #DIVIDE BY ZERO

#### Cause

Your formula attempted to divide an amount by zero (e.g. 4 / 0 provides a divide by zero error).

#### Resolution

Use an IFERROR to return a different value in case the formula were to divide by zero. For example,

=IFERROR(Value4 <> 0, 100/Value4, "")

### #IMBALANCED

#### Cause

The parentheses in your formula do not agree. The number of open parentheses is not the same as the number of closed parentheses.

#### Resolution

Check your formula for extraneous parentheses—add additional parenthesis or remove them as needed.

### #INCORRECT ARGUMENT SET

#### Cause

This error is presented under the following circumstances:

- For functions that take two ranges: The range sizes don’t match for the function.
- The function is missing an argument.
- There is an extra function in the argument.

#### Resolution

Correct the range size or arguments, adding or removing arguments in the formula.

### #INVALID COLUMN VALUE

#### Cause

The formula contains or references a data type that is inconsistent with the column type where it is inserted. For example, this MAX formula is placed in a Text/Number column and references other values in the Date column...

=MAX([Due Date]1, [Due Date]52)

...If the column that contains the formula is not a Date column type, the latest date in the range cannot be returned. (See the MAX Function Help article for more information on how the MAX function works.)

#### Resolution

Make one of the following adjustments to your sheet:

- Type the formula in a different column, one where its type aligns with the type of value that the formula is expected to return.
- Right-click the column header at the top of the column and select Edit Column Properties. Change the column to a type that aligns with the type of value that the formula is expected to return.
- Add IFERROR to your function such that it returns a different value if it encounters the #INVALID COLUMN VALUE error, for example: =IFERROR(“Not a number!”, MAX([Due Date]1, [Due Date]5))
- Wrap your formula in a function that can convert it to the expected data type. For example: =WEEKNUMBER(MAX([Due Date]1, [Due Date]5) when placed in a Text/Number column returns a number that corresponds with the highest date’s week number out of a 52 week period. (More on WEEKNUMBER here.)

### #INVALID DATA TYPE

#### Cause

The formula contains or references an incompatible data type, such as =INT("Hello")

#### Resolution

Make sure the formula references the correct data type.

### #INVALID REF

#### Cause

A reference name to another sheet (in curly braces) doesn’t exist as a reference to another sheet.

#### Resolution

Either change the name within the curly braces to be that of an already created reference to another sheet, or create a new reference to another sheet.

See Formulas: Reference Data from Other Sheets for more information on this process.

### #INVALID OPERATION

#### Cause

Operators (see Create and Edit Formulas for details on acceptable operators) in a formula aren't supported in Smartsheet or are mistyped. For example, this IF statement that returns the text "Low Stock" if a cell contains 25 or less...

=IF(Quantity1 =< 25, "Low Stock")

...has the "less than or equal" to operator in the wrong order; the correct order being <= to make the formula =IF(Quantity1 <= 25, "Low Stock")

#### Resolution

Check all operators to make sure they're not mistyped and are supported by Smartsheet. See Create and Edit Formulas for details on acceptable operators. The most common cause of this is typing <= (less than or equal to) and >= (greater than or equal to) operator combinations in the wrong order.

### #INVALID VALUE

#### Cause

The formula contains a number outside of the range that a function's argument expects. For example, this FIND formula that finds the character "H" in the text string "Hello" has a starting position of 100 characters...

=FIND("H", "Hello", 100)

...Since the string "Hello" is 5 characters long, it isn't possible to have FIND start looking for the character "H" at 100 characters in. Only the numbers 1-5 can be accepted.

#### Resolution

Make sure that all number arguments are within a the range that the function expects.

### #NESTED CRITERIA

#### Cause

You’ve nested criteria in a SUMIF or COUNTIF function.

#### Resolution

Use SUMIFS or COUNTIFS instead, as you can include multiple criteria without nesting.

### #NO MATCH

#### Causes

- The VLOOKUP function hasn't found a result.
- There is not a number within the range that is greater than or equal to the search_value in the VLOOKUP function.

#### Resolution

Adjust the search_value or lookup_table of the VLOOKUP function such that it finds a result. (More on VLOOKUP.)

### #NUMBER EXPECTED

#### Cause

The formula is in a specific type of column (Date, Number, Symbol) and the returned value is of a different type.

#### Resolution

Either move the formula to a different column, or convert the result to the appropriate type. Formula results may be converted to text values by adding an empty string. For example

=TODAY() + "" will allow you to enter today's date into a text column.

### #OVERFLOW

#### Cause

The formula encountered or computed a value which exceeds the supported numeric range. For numeric values the range is -9007199254740992 through 9007199254740992. For WORKDAY calculations, maximum number of days is one million.

#### Resolution

In most cases, this error is caused by inaccurate or incomplete cell references. Check your formula and make necessary changes.

### #PERMISSION ERROR

#### Cause

The formula references data from another sheet (in curly braces), but no one has sufficient sharing permissions to the sheet that contains the formula as well as the source sheet containing the data being referenced.

#### Resolution

Make sure that at least one person is shared to both the sheet containing the formula with Editor-level permissions or greater, as well as being shared to the sheet containing the data with Viewer-level permissions or greater.

### #REF

#### Cause

The formula references a cell which does not exist, possibly due to a row/column deletion.

#### Resolution

Your formulas will need to be updated manually.

### #UNPARSEABLE

#### Cause

The formula has a problem which prevents it from being parsed and interpreted. This can happen for many reasons, such as misspelling, incomplete operators, using the wrong case for a column name, or using single quotes instead of double quotes.

#### Resolution

Ensure that all column names are spelled correctly in cell references, operators are being used correctly, and any text strings in the formula are surrounded by double quotes (" ").

### #UNSUPPORTED CROSS-SHEET FORMULA

#### Cause

The CHILDREN, PARENT, or ANCESTORS functions are referencing data from another sheet (in curly braces), which is not supported.

#### Resolution

Remove the reference from that function. You can create a reference to another sheet and manually select the desired cells. For more information on creating references to other sheets, see Formulas: Reference Data from Other Sheets.
