Movie clip hit state

Hi,

I have some movieclips acting as buttons, what I want to do is give them a visited, or currently hit state.

I have kind of achieved this but when another button is clicked then I need to reset the first button to its original stater# so I dont have more than one button in a ‘hit state’.

The buttons cannot be referenced in any way as there are loads of them in my actual site, so this may not be possible

I have linked an exaple fla that better depicts this.

Hope some one can help,Thanks
