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.

### #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.

### #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, "")

### #ERROR

#### Cause

You cannot have a formula in a contact list column.

#### Resolution

Move your formula to a different column, or change the column type to text/number.

### #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 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

#### Cause

The LOOKUP function hasn't found a result.

#### Resolution

Adjust the search_value or lookup_table of the LOOKUP function such that it finds a result.

### #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. More information on creating references to other sheets is available in Formulas: Reference Data from Other Sheets.
