I keep meaning to come back and thank you all for your answers to my questions, but first I want to apply your answer and see if I can get it to work. And invariably it does work, but fixing that problem reveals a new problem, and I start trying to figure out that one, and forget to to come back and thank you for the original answer. I apologize for the apparent thoughtless. I'm not really unapreciative, I'm just horribly scatter-brained.
