[Zope] Building feedback forms

[Eron Lloyd]

Hello all. I'm just starting my first Zope site, and I'd like to create
a feedback form for the site. I have very little "useful" experience
with DTML, especially for logic. Once I create the form, how do I write
a DTML script to process the input (like linking entries to variables,
testing valid answers, raising errors, etc.) ANY help whatsoever would
be greatly appreciated, and all the useful stuff I learn I'd like to
make a how-to from. Real world solutions like this in Zope are few as
far as documentation go....

thanks in advance,

Eron
