# RELATIVE\_COLUMN
The RELATIVE\_COLUMN identifier returns the value of the column relative to the current column.
## Syntax
```
[Row1].Relative_Column(-1)
```
## Arguments
\[Row1] - Reference to a row
The argument should be a negative number.
## Example
The company is planning to add one more size as Extra Large from January 2014. The expected sales for each month are going to be the same as the previous month's value for the Large size.
Relative\_Column points to the previous month’s value. January value will be applied for February and so on. Since we do not have December 2013 sales, January 2014 will be blank.
Row relative column
If you want to display a value instead of a blank, use IF and Group index as shown below.
Concatenating with IF and GROUP_INDEX
Note that we have used this formula in a template row, so the Extra Large row gets inserted for each category as highlighted in yellow.

## 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/identifiers/relative_column.md?ask=&goal=
```
`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.
