Thanks Chris,

I am a non-programmer, who knew html and a little javascript, that was drawn 
to Zope because DTML was a tag based language.  (Zope is a little cheaper 
than Cold Fusion) I'm trying to learn though.  I thought I had tried using an 
"or" in a dtml-if statement before and it didn't work.  Guess I was wrong. 
Anyway, thanks again for the advice, it works great.

PS. If you know of any schools, org's,  or people for that matter in Northern 
Colorado who teach Python, I would be very interested.
