It has been a while I created my last conditional action, so I’m a bit struggling again.

How to set COMPILATION tag to 1 if ALBUMARTIST=“Various Artists” and delete COMPILATION field (or should it be set to 0?) if ALBUMARTIST is something else.

Any help would be appreciated. 🙂

This could be an action of the type "Format value" for COMPILATION  
Format string: `$if($eql(%albumartist%,'Various Artists'),1,)`
