### How to append the string " xyz" to the content of a tag field?

Create a [new action](https://community.mp3tag.de/t/actions/967/2) in an existing action group and choose Format value as action type.

- **Field** specifies the tag field the formatting rule should be applied to.
- **Format string** must have the field placeholder for the field selected above and the string which should be appended.

**Example:**  
If you want to append the string " xyz" to the current value of the comment field:

_Action type:_ **Format value**  
_Field:_ **COMMENT**  
_Format string:_ **%comment% xyz**

You can use this also to add "xyz " in front of the tag value, combine fields or to copy one value to another field.
