[Zope] Newbie Questions

I am finally starting to make some decent progress with Zope now... more and more I think to myself ... "I wonder if...." and most of the time I am pleasantly suprised when it works! A couple of quick questions: - How would I display the value at a variable whose name is stored in another variable? In Perl this would simply be a double dollar type of affair $name = "Alex"; $myvar = "name"; print $$myvar; - I am creating a 'form' method so I don't have to create separate forms for INSERT and UPDATE actions. This works, only how do I tell Zope to ignore the fact that <dtml-var company_id> doesn't exist when in INSERT mode? It is there in the value="" parameter for the edit mode to pre-populate the element. Thanks in advance Alex
