Hi, I am hoping to get some help with a RegEx.

The first block does not match but the second block does. The difference is that the second block has the pipe character after “greg herman”. It wasn’t obvious to me why the last match string needed a pipe before the closing parenthesis. Any ideas?

Thanks. -Tony
