Thanks for the reply, that helps to clear things up. I was under the impression that by having the widgets defined in interface.h I could reference them directly...in other words, if entryStartNum is defined in interface.h I could just refer to it by that name without having to declare another variable. But I get it now, and I'm past that hurdle and on to the next! Many, many thanks.
