I'm sorry I didn't post here before asking for help twice in the PE3 forum. I just stumbled upon a reference to this section while browsing other posts.
This is the first forum I joined and was attracted to it because of the quick and helpful responses that I have read, especially from Chuck and Steve.
It's not likely that I will be able to offer advice to anybody soon as I am still on "the learning curve", but am looking forward to the day (if it ever comes) that I can be as generous with assistance as you folks!
