Mike, thanks very much. I like your method but now that you mention it, the data would be a problem. I only have 3 boxes anyway, but I believe my license limits me to 2. I will keep IO in mind when the time comes to give it a try. I really appreciate you taking the time for such a detailed answer - thanks again!
