Multi-Step CMS Help

I’m looking to create a CMS dependancy where the user selects a Location (dyn list) and then a Category (dyn list) and is sent to a page where the results show all of the Category selected in the Location selected.

Here is a video example. You can see the user clicked USA and then Supplies but how do I show only supplies with the location USA? I tried filtering the items list but can’t figure out how the CMS would know that the items should match the category selected AS WELL as the location. Is it possible?

The second page in the video is the Category CMS page and the options for filtering are seen in the screenshot below:

08

From this screenshot you can see that I have two separate dynamic lists on the homepage, one for the locations and another for the categories.
