flv mute/unmute playback

Hi,

I have a flv that should play muted on start, with a button indicating the muted position. When un-muted it should play the volume at 70%.

I made a simple button that does this.The problem is when the flv plays again. It starts on volume 0 again.
How can i have it playback at the last toggle, whether it was last muted or unmuted?

I can't seem to override the component paramaters of the flv which is set at volume 0?
i'm using actionscript 2

cheers,
xav

So what i need is help on how to script:

if my mute button is true, than the volume is 70.
else than the volume is 0

do i then just assign that its true on release of the button?

My attempt?:

var myBoolean:Boolean = new Boolean;

if(myBoolean == true) {
myVideo.volume = 70;
} else {
myVideo.volume = 0;
}

and on the button
on(release){
gotoAndStop("OFF");
_root.myBoolean = true;
}
