Hi

I have the disc no as 01 0r 1/2 for all multiple cd albums. Does anyone have a suggestion of how I can add the disc no to the tack number.

ie T=forever  
tr=01  
dn=5/5 ( 5 of 5 discs) in some cases I just have 05

to

T=forever  
tr=501

Thanks

This is possible by using an action Format value

_Field:_ **TRACK**  
_Formatstring:_ **$num(%discnumber%,1)$num(%track%,2)**
