UPDATE: SOLVED as of post #6.
****************
I'm struggling to get the right combination and could use help here. I've looked an a number of threads on this and the "manual" or calibre, but I just cannot get the string combination correct.

I simply want to copy TEXT from this type of pattern to another field.
I just need the regular expression properly tweeked.

This is the title (This is the series 5)
This is the title ( This is the series 5)

I just need a string that gets only the alphabet characters in the parentheses to copy to another field while ignoring any numeric expression. In this case, that would be "This is the series" . Of course, the quotes are just for here and not involved in the actual outcome.

I'm aware of variations and caveats. I know how to deal with everything easily after that. I just need the proper string that will copy "This is the series" whether there is a space or not after the first "(".

Please help. As soon as I think I have some of these expressions down, something doesn't work out, and I just cannot figure it myself.

Thanks.
