Advanced rollover buttons

hello. i am trying to figure out how to get my buttons to stay in the “on” state. i have figured out how to get the button to roll out and change colors when you rollover, but no luck in getting it to work on staying open when you click on a choice. Does anyone know how to do this?

here is the link:
