Kirupasound.STOP!;

Im doing the tutorial “playing sounds with actionscript” in the actionscript tutorials section.

My version works fine, but I seem unable to stop the sound.

I have 2 frames, both with “stop();” in the actions of one of the layers.

In the first frame there is the play button, with the actionscript:

on (release) {
	kirupaSound = new Sound(this);
	kirupaSound.attachSound("coolsound");
	kirupaSound.start(0, 99);
	gotoAndStop(2);
}

In the second frame there is a stop button, with the actionscript:

on(release) {
	kirupaSound.stop;
	gotoAndStop(1);
}

But, “KirupaSound.stop;” does not stop the sound. How can I?
