I assume you're setting your random variable value inside a
double-quoted expression along the lines of <dtml-var
"foo=_.random()"> or similar. If so, remember that every invocation of
the double-quotes is a new Python call, with its own (mostly
read-only) copy of the available namespace.

Unless you modify the existing namespace via something like <dtml-call
"REQUEST.set(foo,_.random())">, foo simply won't be available later in
the object.

I may completely misunderstand the question, but I think that's what
you're asking.
