Hi all, I need some help!

I'm editting my flac collection and I've found that a lot of them have the track and discnumber tags like this:

TRACK = A/BB  
DISCNUMBER = C/D

So I want to split them into TRACK, TRACKTOTAL, DISCNUMBER and DISCTOTAL making mp3tag to auto fill everyone of them.

Something like:

TRACK = A  
TRACKTOTAL = BB  
DISCNUMBER = C  
DISCTOTAL = D

Is there a way I can accomplish this?

Cheers.

MP3tag can split the data like this:  
Action of the type "Guess value" for TRACK  
Guessing pattern: %track%/%tracktotal%

Similar approach for DISCNUMBER:  
Guessing pattern: %discnumber%/%DISCTOTAL%

I am not sure what you mean by "auto fill".

I'm editing my reply because I was implementing what you said in the wrong way.  
I should put %track% in the frist field and %track%/%tracktotal% in the second one, I was using TRACK in the first, now is ok.

Thanks for your help!  
Cheers.

You have not even tried it, have you?  
Because that you described is exactly what an action of the type "Guess value" does.

Didn't notice you have replied.

I did tried it, I was just doing it wrong.

Thanks! My problem is solved now.
