reverse logic?

Hi There,

I made a Tag-Tag action.

Album="AM013_Light Speed"
Album="ATMOS2_French Docs"

Field Discnumber

The data I want to keep is "AM013" however the result is "AM013_Light Speed"..

What am I doing wrong?
Kind Regards

You left out the bit you don't want.
So, just using

would have been enough if the underscore is the separator.

Thank you very much for pointing out my mistake..It works like a charm now
