This is no valid MP3tag scripting syntax.  
I doubt that you can define a format string for a tag panel element, you can select only a field which is read and written to.

If you want to copy the field contents of one field to another, see the FAQs

> How to copy one field value to another field? Example how to copy the content of the ARTIST field to the ALBUMARTIST field: Create a [new action](https://community.mp3tag.de/t/actions/967/2) in an existing action group or make a new action group. Action type: Format value Field: ALBUMARTIST Format string: %artist% Note: If you want to copy all possible values of a field (in case you have multiple artist fields), the internal scripting function [$meta\_sep](https://docs.mp3tag.de/scripting) can be used in the format string, e.g., $meta\_sep(artist,\\\\)

If you want to add contents to a multi-value field, try as  
Format string: `$metasep(composer,\\)\\PL Deer Jade-`
