Why doesn't this work? Simple script

1

The following code is to make the movie stop/start when i click ‘btn1’.

btn1.addEventListener(MouseEvent.CLICK, clicked)

function clicked (event:Event)

{
var stopped:int
trace(stopped)
if(stopped==0)

{
	stopped=1
	this.stop()
}
	
else

{
	stopped=0
	this.play()
}

}

The movie stops when i click it, but never resumes. Also the trace always shows ‘stopped’ as 0. Any help would be appreciated.
