# FILTERIF

The FILTERIF function can be used to filter an array of values based on a given condition. It returns an array, hence it has to be used in conjunction with an aggregate function like SUM or AVERAGE. It can be used to populate a [calculated row](/premium-table/working-with-premium-table/4.-adding-business-logic-and-formulae/insert-calculated-rows.md).

## Syntax

```javascript
filterif( list, condition)
```

## Arguments

list – The input list of values on which the filter is to be applied

condition – The condition to be evaluated

## Return value

Returns an array.

## Example 1

```javascript
sum(filterif([United States].DESCENDANTS, ROW.LABEL = 'Soda'))
```

The formula above will use FILTERIF to filter all the rows under Region 'United States' with category = 'Soda'. It will then sum up all these values column-wise.

Example 2

```javascript
average(filterif([Column1,Column2,Column3],">1000"))
```

Returns the average of values in Column1, Column2, and Column3 if they are greater than 1000

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.inforiver.com/premium-table/formula-syntax/conditional-statements/filterif.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
