[Zope] How to access a dtml-var from a python method?

[Rommel Novaes Carvalho]

Hi everybody,
 
             I would like to know how can I access a variable that I have on
a html form, for instance, in my python method and work with this variable
in python? I tried to pass as a parameter, like 
    def method(<dtml-var variable>):
         ...
         if <dtml-var variable> == ...
 
and of course it did not work, I would be really glad if any of you could
help me.
 
         
 
                                                    Thanks in Advance,
                                                        Rommel Novaes
