CS3 Sound On/Off Button In Movieclip?

I'm trying to make a button that when clicked executes a sound clip and plays all the way through. Also, if the button is clicked while the sound is still playing the sound needs to stop. They have me first place this code in the first frame:

my_sound = new Sound();
my_sound.attachSound("bubble_01sound");
play();

Next I create two buttons, an on and an off which are placed separately in the second and third frames respectively. Code is applied directly to the buttons.

The on button:

on (release) {
_root.my_sound.start(0,1000);
_root.gotoAndStop("stop");

[code]...

Finally, I name the 2nd frame "play" and 3rd frame "stop" and add stop(); to both frames. Oh I also set up the linkage so that the sound's identifier is "bubble_01sound".

This is all well and good however, here's the rub. Unlike their example which takes place in the main timeline, my button needs to bob up and down. So I put everything from the tutorial in a movieclip and on the main timeline animate the movieclip as I like. When this plays the button does not play sound. I took this as the initial sound code not being activated because its in the movieclip. If I take the sound code out of the movieclip and place it in the first frame of the main timeline, the button does play sound but the stop function does not work. I can keep clicking the button which repeats the sound on top of the already playing sound.

So it seems to me there are three options. One, I need to find a way for the sound code to be activated when its seated in the movieclip. Or two, with the sound code in the main timeline, I need a way for the on/off buttons to reference the code which is one level up in the main timeline. Or the third option would be that I'm completely wrong... I'd put my money on the third option.
