[Zope] OOPS: [Zope] NEWBIE: DTML Appending string and passing in REQUEST?

[Roddy]

Hye thanks Chip, this is the kind of thing that should be in a HOW-TO
(DTML tutorial actually), it begins to solve my problems quite nicely.
One of the things that bug me with the DTML tutorial thing in the
documentation section of zope.org is that it's so bare of example code, it
gives information but it's really hard to put together! Especially not
being a python person.
