I just want to send a "Thank You" to DavidR, but I am not even sure how to do that. He was very helpful, and I am grateful for that. There is no question that I am totally lost using this forum - I find it to be incredibly confusing. I am hoping this "Thank You" note is going only to DavidR but I suspect it will reach a wider audience... I don't know how wide. Sorry that I am completely lost using this Forum. Anyway, Thanks to DavidR. It worked. Sincerely, Richard Oppenheim, Ph.D.
