Hello - I have this Flash map that I've created. It uses javascript calls from
within Flash to swap out hidden DIVS when a user clicks on a county. When the
user clicks on the zip code region of that map, a javascript triggers the check
box.

What I need to do now is to have a way that when a user unclicks the check
box, the zip code region in the map will be unhighlighted. Essentially, I need
to have javascript tell a movie clip within the .SWF file to goto a certain
frame and stop.

I've never done this before, so I'm seeking someone's wisdom on how to proceed
with this.
