How Can I put the code Play And Stop Button in Flash Cs6

[OwenSiriwat]

So I have a project to send my teacher in Adobe Flash Cs6. I make the Wheel Spinner. At this time I am confusing when I put the code on the button start and stop I use the code
on (release) {

Wheel_mc.play();

}
and

on (release) {

Wheel_mc.stop();

}

So Anyone can help me? to spin the Wheel for my fortune !
