Well unfortunately the first one did the trick. Unfortunately, because
this causes some other problems (this was just a short example). I need
those variables in the current namespace. But now I do have a basic idea
of what needs to be accomplished and I think I can take it from here.
Also after reading up a little more on Zope doc's I get the feeling that
I should be doing this with page templates instead. Any comments,
suggestions?
Thank you for your response,
Patrick
