[Zope] dtml-if syntax and comparing variables

[Roché Compaan]

Thanks Kevin, it works.

But the solution to the problem really makes me sigh deeply.  I currently
have more solutions than understanding.  The Zope Quick Reference quickly
mentions "this" as "a handy way to talk to ourselves in document templates".
I am familiar with "self" in many programming languages and "self" would
have enlightened "this" issue a bit.

I am not giving up because I just see too much potential in Zope.  I love it
but in many ways it's like a problematic child.  I don't have any strategy
in approaching the Zope Object Framework, except maybe that I'll have to
learn Python (which I'm busy with) and start digging into the code - is this
the only way?  Simple issues arise:

1.What are the rules for using quotes in dtml?
2.The nitty gritty of passing, comparing and setting variables in less than
6 hours.
3.How does one properly cross the chasm from rendering variables to
evaluating them in expressions.

Hopefull
