Also, Don, you really don't want to use DTML for that kind of stuff. Better
to direct the posting of the form to a pythons script ("Script (Python)" as
they are called in the ZMI) and then generate error messages form there and
then either redirecting to or calling a DTML-method to report
errors/success.

Doing all that in DTML is way to hard to be worth the effort - been there,
done that - and you'll be able to write code that traps errors in a much
nicer way than you can do in DTML - and as a bonus you will find that yopur
code will easier to write and debug.

My 2 <insert lowly currency here> worth.
