reverse logic?

Hi There,

I made a Tag-Tag action.

Album="AM013_Light Speed"
Album="AMB15_kara"
Album="ATMOS2_French Docs"

Field Discnumber
$regexp(%Album%,(\u{1,3})(\d{1,4}),$1$2)

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.
$regexp(%Album%,(\u{1,3})(\d{1,4}).,$1$2)
So, just using
$regexp(%Album%,(.
)_.*,$1)

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
