Yeah, I realized the += mistake (as in I should have used that) after I had posted it and saw it in front of me. I went back and changed my actual code.

The "each" recommendation is new to me. I'm certainly not a Perl expert (yet), so I rely on the faithful "foreach" when I want to do something "for each" member of a group. Thanks for the tip, I'll read up on that and try it out.
