Mute Button ?

Hi I want to add mute button to my movie using dot notation code. Using one button it should mute / unmute the sound. Thanx.

First frame of the main timeline...

myGlobalSound = new Sound(this);

On the button...

Code:

---

on (release) {
        if (muted = !muted){
                myGlobalSound.setVolume(0);
        }else{
                myGlobalSound.setVolume(100);
        }
}
