And you certainly were much more couteous and respectful.
Thank you.
I wasn't expecting anyone to write all of that though I do
appreciate it. I was just hoping someone would know of a free or an
inexpensive pay script to solve my problem and give me a URL or
something to find it.
I'll look your coding over. Maybe I can figure it out well
enough to code it into my page. .
Regards, and thanks again,
Fred
