Breadcrumbs on a flash button?

I am trying to show my visitors where they have been on my site by including a breadcrumb function to my buttons. So when someone clicks on a button to look at one of my projects it turns grey, then when they click on another button in my flash site the prior button they clicked on stays grey.

As long as the browser doesn’t get refreshed, all you have to do is make your buttons out of movieClips because you can apply all the actions of a button on a movieClip. Make the second frame of the movieClip your grey button. Then in your actions, tell the movieClip to goto the second frame. It will never automatically go blank:


on(release){
this.gotoAndStop(2);
//also whatever your buttons going to do for instance:
_root.gotoAndStop("substance");
}

Thanks I just tried it and it worked on its own. When I get home I will try it on my site.
