Hello I would remove disencumber metadata for every item who have only one disc
I tried
$if($eql(%DISCNUMBER%,1/1),,%DISCNUMBER%) and $if($eql($len(%discnumber%),1),,%discnumber%)
but it does not work, also it create a space, i would have 0 byte of data on this field in this case,
thank you for your assistance

You could try an action of the type "Format value"
Format string:`$replace(%discnumber%,01/01,,01/1,,1/01,,1/1,)`
I see problems, though for files that are disc number 01 of 10 (11, 12 etc) as "01/1" matches that. The same problem arises for 1/1.

Thank you, this recommandation only replace 1/1 by 1, my problem is that I don't want a discncumber If there is only one disc then written 1/1 OR 01/01 OR 1 OR 1/01 OR 01/1, I need two actions ?

I corrected my original post and removed the typo - could you check again, please?
