I already tried my *** off.
I want a format string that:
-
if there is no " // " just copy everything in the tag "Artist" to "Album Artist"
-
if there is " // " just copy everthing before the first " // " from "Artist" to "Album Artist"
I already tried this but if there is no " // " it leaves "Album Artist" blank:
$if($strstr(%artist%, '// '), $left(%artist%, $sub($strstr(%artist%, '// '), 1)), %artist%)
