=SUMIF(Done:Done, 1, Cost:Cost)

Result: 300

=SUMIF(Cost:Cost, < 200)

Result: 250

### SUMIFS (Advanced Function)

#### Description

Adds numbers within specific cells or range that meet criteria.

#### Syntax

SUMIFS(sum_range, criterion_range, criterion, criterion_range, criterion, ...)

The SUMIFS function takes the following arguments:

- sum_range—Collection of cells (typically adjacent to the criterion range) that you want to sum, assuming they meet all criteria.
- criterion_range—Collection of cells you want to evaluate with the criterion.
- criterion—Value, such as a text string or number, that you want to locate in the criterion range.

#### Example

=SUMIFS(Cost:Cost, Done:Done, 1, [Task Name]:[Task Name], "Task A")

Result: 100

### TODAY (Date Function)

#### Description

Returns the current date. Displays today's date in a Date column. When used in other formulas, it can be used to compare other dates with the current date.

#### Syntax

TODAY(*numeric_value*)

The TODAY function takes the following argument:

*numeric_value*(optional)—Number of days before (negative number) or after (positive number) the current day.

#### Example

Dates in the following examples are in US format (mm/dd/yy).

=TODAY(-5)

Returns five days *before* the current date. If today’s date is 11/8/16, the result would be 11/3/16.

=TODAY(5)

Returns five days *after* the current date. If today’s date is 11/8/16, the result would be 11/13/16.

=[Due Date]1 - TODAY()

Result: The number of days between today and 11/01/13.

### UPPER (Text Function)

#### Description

Converts any lowercase characters to uppercase.

#### Syntax

UPPER(text_value)

The UPPER function takes the following argument:

- text_value—A text value or reference to a cell containing a value.

#### Example

=UPPER([Task Name]4)

Result: TASK D

### VALUE (Text Function)

#### Description

Converts a text value (that represents a number) to a number.

#### Syntax

VALUE(text_value)

The VALUE function takes the following argument:

- text_value—A text value or reference to a cell containing a text value.

#### Example

=VALUE(LEFT(Cost5, 3)) * 4

Result: 1700

#### Notes

- You can use the VALUE function within another function to ensure that a numeric value will be returned from your formula. Certain formulas will always return a value in text format, even if it looks like a number. This will return an error when you attempt to perform numeric calculations on a text value, such as in the example below:

=LEFT(Cost5, 3) * 4

Result: #INVALID DATA TYPE

The =LEFT(Cost5, 3) portion of the formula returns the value 425, which looks like a number but is actually stored in Smartsheet as text. Use the VALUE formula to convert text to numeric format so that the formula doesn’t produce an error.

### WEEKDAY (Date Function)

#### Description

Returns the number for the day of the week, where Sunday equals 1.

#### Syntax

WEEKDAY(date_value)

The WEEKDAY function takes the following argument:

- date_value—The referenced cell (must be of a Date column type) or other date value.

#### Example

=WEEKDAY([Due Date]5)

Result: 7

### WEEKNUMBER (Date Function)

#### Description

Returns the number of the week in the year.

#### Syntax

WEEKNUMBER(date_value)

The WEEKNUMBER function takes the following argument:

- date_value—The referenced cell (must be of a Date column type) or other date value.

#### Example

=WEEKNUMBER([Due Date]5)

Result: 9

### WORKDAY (Date Function)

#### Description

Returns a date that is the specified number of working days before or after a date.

#### Syntax

WORKDAY(date_value, number_of_days, *holiday_range*)

The WORKDAY function takes the following arguments:

- date_value—The referenced cell (must be of a Date column type) or other date value.
- number_of_days—A numeric value representing the number of days before (negative number) or after (positive number) the referenced date cell.
*holiday_range*(optional)—A group of cells (must be of Date column type) containing holidays to exclude.

#### Example

=WORKDAY([Due Date]1, 365, [Due Date]2:[Due Date]3)

Result: 3/30/15 (US date format)

=WORKDAY([Due Date]5, 6)

Result: 3/10/14 (US date format)

#### Notes

- By default, the WORKDAY, NETWORKDAY, and NETWORKDAYS formulas count Saturday and Sunday as non-working days. If dependencies are enabled on your sheet you can customize the non-working days, and the formulas will use your settings in calculations.
- You can designate other dates as nonworking to exclude them when calculating the new date. To do this, enter each holiday/non-working day into a cell and then reference the range of cells in your WORKDAY formula.

### YEAR (Date Function)

#### Description

Returns an integer as four digit year, in numeric format.

#### Syntax

YEAR(date_value)

The YEAR function takes the following argument:

- date_value—The referenced cell (must be of a Date column type) or other date value.

#### Example

=YEAR([Due Date]5)

Result: 2014

### YEARDAY (Date Function)

#### Description

Returns the number of the day in the year on which a specified date occurs.

#### Syntax

YEARDAY(date_value)

The YEARDAY function takes the following argument:

- date_value—The referenced cell (must be of a Date column type) or other date value.

#### Example

=YEARDAY([Due Date]5)

Result: 60

### Using Hierarchy in Formulas

Hierarchy formulas allow you to roll-up information found on child rows of the referenced parent row. If placed on the parent row in the column with the data to be utilized, the syntax is **=COUNT(CHILDREN())** with empty parentheses. If not placed on the parent row above the data to be utilized, you must include a reference to the parent cell within the desired data column e.g.**=SUM(CHILDREN([Total Hours]14))**.

The following functions can use CHILDREN() as a parameter: AVG(), COUNT(), COUNTIF(), MAX(), MIN(), SUM(), SUMIF(), AVGW().

TIP: Learn about creating parent and child rows in our Hierarchy: Indenting & Outdenting rows article.

### Using @cell in Formulas

When you want to perform calculations in formulas that use SUMIF(), SUMIFS(), COUNTIF(), or COUNTIFS(), you can use the @cell parameter in the criteria of the function. The @cell parameter performs a calculation on each row at the same time that the primary function (SUMIF for example) is evaluating the criteria in the range; this makes your formula more efficient.

For example, using the sample data, if you wanted to sum the cost of all tasks whose due date occurred in 2014, you would create the following formula:

=SUMIF([Due Date]1:[Due Date]5, YEAR(@cell) = 2014, Cost1:Cost5)

The result of this formula is $875.75 (the sum of the cost for all tasks whose due date occurred in 2014).
