Changing scene (timer event)

programming flash
1

What could be the possible reasons for ArgumentError: Error #2109: Frame label off over not found in scene Scene 1.
at flash.display::MovieClip/gotoAndStop()This code appears after my timer has finished and is supposed to change scene (a timer event).


function timerLeft1(seconds:int):void
{
    var t1:Timer = new Timer(50, seconds*thickness1);
    
    // graphic element
    var w1:Number = thickness1;
    var h1:Number = stage.stageHeight-thickness1;
    var g1:Sprite = new Sprite();    
    addChild(g1);
    
    // find percent and draw it!
    t1.addEventListener(TimerEvent.TIMER, onTimer1);
    function onTimer1(evt:Event):void
    {
        var cc1:int = evt.target.currentCount;
        var gHeight1:Number = (cc1 * h1)/(seconds * thickness1);
        g1.graphics.beginFill(0xB0471C);
        g1.graphics.drawRect(0, stage.stageHeight-thickness1, w1, -gHeight1);
    }
    t1.addEventListener(TimerEvent.TIMER_COMPLETE, onComplete1);
    function onComplete1(evt:Event):void
    {
        gotoAndPlay("1, win");
    }
    t1.start();    
}

aroundTimer1(timerDuration1); 
stop();

I’ve basically drawn a timer on stage, followed by a listener changing the scene once the timer has expired.
I don’t see any errors in the code, but is there perhaps anything preventing it from changing the scene in the aforementioned code?
