goto a frame when an array is empty

[MarkSensei]

Im wondering, I have this script courtesy of MD004 (thanks again)
and Im wondering how I can make it goto the frame labeled "congradulations" when the array is empty. this is what I have.

function arrayRandomizer(a, b) {
	var value = (random(2)==0) ? -1 : 1;
	return value;
}

frames = [2,3,4,5,6,7,8,9,10,11,12,13]; // this is the array of frames
frames.sort(arrayRandomizer);


currentFrameCount=0;
function nextFrame() {
	gotoAndStop(  frames[currentFrameCount]  );
	currentFrameCount++;
}

I tried just putting a

if( frames == "" ){ 
 _root.gotoAndPlay("congradulations");
}

but it doesn't goto the frame
any suggestions?

thanks in advance
