[Zope] Accessing a dtml-let variable in a script (python)

Is it possible to access a variable in a python script which was created in a dtml-let tag. Thought it would be simply a matter of referencing it using context.variable_name but this doesnt work. Also thought it may have been accessed thru the namespace setting in the script, but could not work it out. Thanks for any ideas.
