How to stop a movie clip

programming flash
1

I’ve got timer below and after sometime he calls function credits…

var wait:Timer = new Timer(3000);
wait.addEventListener(TimerEvent.TIMER, credits);
//Start the timer
wait.start();

where he says to my movie clip creditLine to start. That is OK.

creditLine.visible = false;
function credits (evnt:Event):void
{
creditLine.visible = true;
creditLine.gotoAndPlay(“theStart”);
}

…but I don’t know how to stop that movie clip. I tried to put stop(); at the end of the movie clip but it messes up the whole fla.:h:
How do I stop the movie clip. The end has label “theEnd”

Please
