Hello all,
I have a long list a albums from a audio series that look like the following: "01\_album name" and trying to make them look like the following "01\_album name(Vol. 01)". I clicked on actions and "Replace with regular expression". Field is ALBUM, Regular expression is: ^(\d\d), and Replace matches with is: %album%(Vol. $1). When use the Action, I get: %album%(Vol. 01)\_album name. Am I going about this all wrong or is there something I am not seeing here.
Thanks,
daring\_t

Try:
Search pattern: `^(\d\d)_(.*)`
Replace with: `$1_$2(Vol.$1)`
