This is not the proper syntax ...  
$validate(something,blah,blah)

See Mp3tag Help Manual.  
The function $validate(filename,to) replaces all invalid characters, regarding the creation of filepathnames, with one dedicated character, chosen by the user.  
Some invalid characters are: **/?\*"\<\>|:**  
Example: **$validate(%ARTIST%' - '%ALBUM%' - '%TRACK%' - '%TITLE%,'\_')**  
Example: **$validate(%ARTIST%' - '%ALBUM%' - '%TRACK%' - '%TITLE%,)**
