Hi Margie,
I'm not sure off the top of my head, but if memory serves me right,
template tags may not allow variable number of parameters. I'd take a
look at the code from the {% url %} template tag, it's syntax allows
for multiple variables, but they're passed in a very particular way.
It's actually some very straightfoward but powerful code in the core
and a great place to start getting to konw djano a little better.
I've done some similar stuff to create template view requests (a more
rails way of thinking about things) as well as a tag for partial urls.
Cheers
Dan
