Need help creating time based movie control

Hello all.

I’m trying to create “Time based movie control” (in the first frame of my movie) via the code below. I’m trying to advance the playhead to frame 2 once 5000 milliseconds have gone by. I’m able to trace getTimer but I am unable to advance the playhead to the next frame.
Any thoughts?
stop();
function myTimer():Void {
trace(getTimer());
if(myTimer > 5000){
gotoAndStop(2);
}
}
var intervalID:Number = setInterval(myTimer, 1000);
myTimer();
Cheers,

-A
