>Thanks for the extra advice!!! I am amazed at this site and how it works - I am new here - is it customary to reply to everyone who writes???!!!!

It is. There is a real hunt for the questions and unofficial contest who answers faster (the record as I recall is 26 seconds). Sometimes it happens nobody knows the answer, but we have "Unanswered threads" link, and everybody is welcome to make this link always empty.
