# Add values

This action can be only performed on a file, gallery, multi-select, and product relation type attributes. 

This action adds value to existing ones without deleting them.

Other than that, the behavior is the same as with [Change values ](https://usermanual.ergonode.com/products/catalog/batch-actions/edit-attribute-values#change-values)action.

{% hint style="info" %}
It's also possible to use attribute variables here. Read more on how to use them [here](https://usermanual.ergonode.com/products/catalog#attribute-variables).&#x20;
