Stopping the sound!

hello,

i have programed a play button using:

on (release) {
kirupaSound = new Sound(this);
kirupaSound.attachSound(“coolsound2”);
kirupaSound.start(0, 1);
}

now i am trying to program the stop button to allow the user to stop mid song…

does anyone have the actionscript for this?!?!?!?

thanks.
