I have set-up a conditional category drop-down selection with four different specific forms. Essentially, someone who selects "film submission" will get the fields necessary to submit their film, or someone can select "advertising" and get the proper forms to submit their advertising information.

What I want to do is see if there is a way to set up a url that will automatically select a certain category's drop-down options. I thought I could use http://www.cinemafunk.com/contact.html?category=film_submission using %get[category] has a default value, but to no avail. Tried a few things from Working with Default Values (http://drupal.org/node/296453), but I still haven't wound up with what I'm looking for. Is this possible?
