Due to some hysterical, I mean historical reasons you cannot simply
"call" a DTML Method unless you pass in a few things.

A DTML object needs a context in which to render itself.  This context
can be passed in one of three ways, as a 'client' object, a 'REQUEST'
mapping (any mapping) or as keyword arguments to the method.  For
example:

<dtml-var "calledmethod(_.None, _, testvar=value)">

is one way to do what your looking for.  _.None is the client (None), _
is the current namespace stack (thus the method will render itself in
the current context) and 'testvar=value' is a keyword argument for your
variable.
