Hi,
I am so sorry. Everything works terrific, and that formula I understand

I should have posted that day right after I tried it, but I put it off while I packed to go out of town and just plain forgot. I just got back yesterday, please accept my apology. I am usually not so flighty.
I thank you very much for all your time and your help. I hope that you will continue to help me when I post my next question, and there is another question, but on a different issue, so I think I should post it as another topic, once I figure out how to ask it

I promise to post back immediately from now on.

and thank you again so very much.
