Action to

hi

I have the action to '01 - only first letter in caps' but I want to "upgrade" to '01 - Only first letter in caps' where 01 is track number and 'only first letter in caps' the title of the song.

thank you.

Are we talking about the field TITLE or the filename?

To get the first letter of TITLE in capitals use an action of the type "Format value" for TITLE.
Format string: $replace(%title%,$left(%title%,1),$upper($left(%title%,1)))
