Clear interval :(

1

Im using a function found in this forum to simulate a timer


var numTimeLimit = 60000;
var bolFirstTime = true;
function countDownF() {
	if (bolFirstTime) {		
		numTimeStart = getTimer();
		bolFirstTime = false;
	}
	numTimePassed = getTimer()-numTimeStart;	
	if (numTimePassed>numTimeLimit) {		
		trace("done");
		clearInterval(countDownI);
		
	}
}

I just can’t find a way to pause that timer… Also if i move to frame 2 (this is frame 1) and move back to frame one, it doesn’t seem to stop…

can someone help me out please??
