I tried this too but zope return an error ('Type Error, unsubscriptable object').

Exactly this is my case:

I've a class called, for example, pippo. This cotain another class called pluto.

So wath I'd like to do is:
    <dtml-with pippo>
      <dtml-with pluto>
        <dtml-var expr="ciccio('parameter')">
      </dtml-with>
    </dtml-with>

the expr or method ciccio doesn't exist in pluto but I'd like to pass to a defined method the expr and its parameters.

A big thanks anymore for your help

bye,
