That _should_ work. 
In DTML, I think when you ask for something it does a options,
REQUEST, context, acquisition context lookup all in one loop. In TAL
you can't be lazy :( and you have to specify exactly where you expect
it to come from.

Bare in mind that keyword arguments only span across ONE template
where as variables in REQUEST span across ALL templates.

Doublecheck your template usage and/or send us your traceback.
