# Rule action: Combine value

### Use cases

* Fill or add content to fields with a combination of text or numbers from other fields

Use the **combine value** action to fill a field with contents of other fields and/or a static value of your choice.

### Add colors to product titles to improve visibility

You can use **combine value** to add color and/or size information to the title or the ID of an item. This can improve your item's performance on export channels.

{% hint style="info" %}
Important: The condition IF color isn't empty ensures that you only add the "- color" to the title when there is a color available. Otherwise, you would have titles ending with a "-" for the items where the color field is empty.
{% endhint %}

The results are titles with the item color added:

* Durea Instapschoenen 5669 - Taupe
* Teva Sandalen & slippers Kayenta - blue combi
