[Zope] Newbie DTML: How do you just declair a veriable.

I am sure that this has been asked before but for some reason I cant find the answer. I am developing a small application and in part of it I want one page to recursively call itself and display a new sub-page depending on which link was clicked on. I am trying to just create a variable that I can set to the new method but I always get an error. How do you just make an arbitrary variable. I tried <dtml-var somename> = <dtml-var somemethod> and it did not like that complained about there not being a somename well that's what I am trying to make. -Bryan
