I dont really understand the outside loop either.  It was grafted from
another page and will be rewritten correctly once I understand the whole
system a little better.

As always the explanation caused that dim little light in my brain to shine
a little brighter :)  Thanks!

I would agree. In a production environment I would always store the code not
the name.  I have been learning and this is really just a proof of concept
page that I'm working on.

Thanks again for the valuable insight!
