Barbara,

>Please keep posting - Keep in mind that the people who know the answers just made the same mistakes earlier than you did. And some of us are giving out answers that WE got from earlier messages :-)

... or that we just learned by duplicating the other person's problem, then searching for an answer. Sometimes I think I learn more from troubleshooting other peoples' code than from my own, since they may be using commands that I don't normally use, etc...
