I lost default values

I need help and I speak little English.

I accidentally deleted the default values of the column "Album Artist"
Can you give me these three values:

Value : 
Field : 
Sort by :

Thanks in advance

Try this adaption ...

Name : AlbumArtist Value : $if2(%ALBUMARTIST%,$if2(%ALBUM ARTIST%,'? '$if2(%ARTIST%,%_filename_ext%))) Field : %ALBUMARTIST% Sort by: $if2(%ALBUMARTIST%,$if2(%ALBUM ARTIST%,'? '$if2(%ARTIST%,%_filename_ext%))) Numeric: no


Thank you very very very much !!!
