Problem with actions to move everything from ft. to end of filename

[ReyRaym]

Trying to move ft. and everything to the right of it from filename to artist.

So this only works correctly if I filter just ft.
Gives me name already exist error if I don't filter.
Feel like this could be another "DUMMY" issue, changed action types, tried a few other things, but can't get it to work without filtering.

Format tag field “ARTIST”:%artist% $mid(%_filename%,$strstr(%_filename%,'ft.'),$len(%_filename%))

Format tag field “_FILENAME”:$if($strstr(%_filename%,'ft.'),$left(%_filename%,$strstr(%_filename%,' ft.')), $ignore_error)

Format tag filed “_FILENAME”:$trim(%_filename%)

Looks pretty darn similar to your other topic.

Artist to Albumartist action

I have this action group, with 3 actions. It basically copy's artist to albumartist, then trims off anything from "ft." to the end of the field. The good is that it works perfectly if the artist has a featured artist in the field. The bad is that if the artist doesn't have "ft." in the field, it removes the tagging from the albumartist field, leaving it blank. I have tried tweaking it, but keep getting the same outcome. Anyone have a solution for this? Import tag fields “%ARTIST%”:%ALBUMAR…

Change %Albumartist% to %_filename% is about the only difference?
