Need help to using a dropdown select list to change dynamic content on a page

Need help to using a dropdown select list to change dynamic content on a page

I am not a programmer by any means and no very little about scripting. I
could really use some help from someone who knows the ins and outs...
I am trying to recreate the actions on the following page:
http://www.redkensalon.com/distributor-locator/
What I would like to happen is for the visitor to see the drop-down menu
of states, when they select their state, it brings up the distributors
coded for their state (region)
I am using wordpress and can easily add custom CSS and Java but I don't
know what I need to do to make this work.
I am currently stuck at this point: http://norvellpro.com/?page_id=2947
The drop down action is just not functioning so I know it is a scripting
issue.
Any help is GREATLY APPRECIATED!
