That would be very easy with JavaScript and CSS like jbennet said. You just need 1 or 2 lines of code that does exact same thing.. but if you're insist to use JavaScript or CSS, you can use flash, this would be your lines of code:
Code:
on (release) {
gotoAndPlay(15); // can be nextFrame();
} That's going to assume that on Frame 15 there's going to be another buttom. And vice versa, on Frame 15 you put the exact same code, but pointed toward the first frame
