Mute Button in Action Script 3 - actionscript-3

Question

So here is my question. I have a expandable banner. When expands a video is starting to play. My task was to insert an on/off button for the sound in the video, and i did that. But the problem is that i can't reach my button because when i try to move the mouse to the button the expandable area disappear because I'm moving to the button areas. Here is the code too.
import flash.events.Event;
import flash.net.URLRequest;
import flash.events.MouseEvent;
import flash.media.SoundTransform;
import flash.media.SoundMixer;
cierre.gotoAndStop(1);
SoundMixer.soundTransform = new SoundTransform(0);
video_player.autoPlay = true;
video_player.source = "video_500x374.f4v";
video_player.addEventListener(Event.COMPLETE, finVideo);
stop();
b2_btn.buttonMode = true;
b2_btn.addEventListener(MouseEvent.MOUSE_OUT, aBanner1);
b2_btn.addEventListener(MouseEvent.CLICK,onClick);
var clicktag=(stage.loaderInfo.parameters.clickTag)? stage.loaderInfo.parameters.clickTag:"http://www.vasava.es";
function onClick(e:MouseEvent){
navigateToURL(new URLRequest(clicktag),"_blank");
}
function aBanner1(e:Event):void{
video_player.stop();
this.gotoAndStop(1);
}
function finVideo(e:Event):void{
video_player.stop();
cierre.play();
}
function setMute(vol) {
var sTransform:SoundTransform = new SoundTransform (0,1);
sTransform.volume = vol;
SoundMixer.soundTransform = sTransform;
}
var Mute:Boolean = false;
mutebutton.addEventListener (MouseEvent.CLICK,toggleMuteBtn);
function toggleMuteBtn (event:Event) {
if(Mute) {
Mute = false;
setMute(0);
}else{
Mute = true;
setMute(1);
}
}

Either put the mute button in the expanded portion of the banner itself, or just have the expanding banner mute the audio automatically with no need for a second button push. Which to use depends on your specific application and client requirements.
