Talking from Iframe to Iframe?

I am doing a site with a top flash nav, and Iframe with some flash and html in it.

Is there a way to have the flash in the Iframe give actions to the flash nav??

you can see it here:http://www.dyaddesigns.com/roque_new_layout/

when you hit the porperties button, i want the nav to change to FOR SALE.

something like:

on (release) {
_level0.clip.gotoAndPlay(2);
}

I hope this make sense :thumb:
