[Zope] change variable

I want something like this: flag=0 if ...: <dtml-in ...> ... flag=1 </dtml-in> endif if not flag: print something else endif But I can't figure out how to change a variable initialized by <dtml-let flag='0'>. How can I do this? This is really frustrating, I feel like a total idiot asking for help about such a basic thing!
