Button Press

OK, i think this an easy one.

I want to have a button with a rollover state that is different that the out state. I got that part, but I also want to keep the rollover state active if clicked. I can think of a couple ways to do it but I’m certain there is an easier way to do it. I have about 8 buttons and when I click on on I want that to stay in the rollover state, then when I click on another one I want the first to go back to the out state and the new one that I clicked to go to the over state and stay there.

Any thoughts?
