Too many eventListeners in nested form causes falsh cs6 debugging session to crash ?

Question

Hello all !
The above video (http://www.youtube.com/watch?v=53vqkd5VLFw) is that of a simple sequential click game. The code works perfectly in a simple situation of just nine movieclips or even upto 20 movieclips or so. But when i increase the numbers of movieclips further and adds more eventlisteners in nested form, the flash cs6 debugging sessions seems to get overloaded and fails to give a result. It simply gets hanged.
Working Code for a simple situation:
startBtn.addEventListener(MouseEvent.CLICK, trigGame)
function trigGame(e:MouseEvent):void{
//n1 to n9 are the nine movieclips arranged in grid form
n1.alpha = 1;          n2.alpha = 1;          n3.alpha = 1;
n4.alpha = 1;          n5.alpha = 1;          n6.alpha = 1;
n7.alpha = 1;          n8.alpha = 1;          n9.alpha = 1;
startBtn.visible = false;
//GRID SHUFFLE CODE:OPEN
function randomSort(a:*, b:*):Number
    if (Math.random() < 0.5) return -1;
    else return 1;
var positions:Array = [new Point( 158, 296),new Point(238, 296),new Point(318,  296),
new Point( 158, 366),new Point( 238, 366),new Point( 318, 366),new Point(158, 436),
new Point( 238,436),new Point(318, 436)];
var mcs:Array = [n1,n2,n3,n4,n5,n6,n7,n8,n9];
positions.sort(randomSort);
var q:int = positions.length;
for(var t = 0; t < q; t++)
    var mc:MovieClip = mcs[t];
    var point:Point = positions[t];
    mc.x = point.x;
    mc.y = point.y;
//GRID SHUFFLE CODE:CLOSE
{n1.addEventListener(MouseEvent.MOUSE_DOWN, alph1);
function alph1(e:MouseEvent):void
{{n1.alpha = .5;n1.removeEventListener(MouseEvent.MOUSE_DOWN, alph1);};
n2.addEventListener(MouseEvent.MOUSE_DOWN, alph2);
function alph2(e:MouseEvent):void
{{n2.alpha = .5;n2.removeEventListener(MouseEvent.MOUSE_DOWN, alph2);};
n3.addEventListener(MouseEvent.MOUSE_DOWN, alph3);
function alph3(e:MouseEvent):void
{{n3.alpha = .5;n3.removeEventListener(MouseEvent.MOUSE_DOWN, alph3);};
n4.addEventListener(MouseEvent.MOUSE_DOWN, alph4);
function alph4(e:MouseEvent):void
{{n4.alpha = .5;n4.removeEventListener(MouseEvent.MOUSE_DOWN, alph4);};
n5.addEventListener(MouseEvent.MOUSE_DOWN, alph5);
function alph5(e:MouseEvent):void
{{n5.alpha = .5;n5.removeEventListener(MouseEvent.MOUSE_DOWN, alph5);};
n6.addEventListener(MouseEvent.MOUSE_DOWN, alph6);
function alph6(e:MouseEvent):void
{{n6.alpha = .5;n6.removeEventListener(MouseEvent.MOUSE_DOWN, alph6);};
n7.addEventListener(MouseEvent.MOUSE_DOWN, alph7);
function alph7(e:MouseEvent):void
{{n7.alpha = .5;n7.removeEventListener(MouseEvent.MOUSE_DOWN, alph7);};
n8.addEventListener(MouseEvent.MOUSE_DOWN, alph8);
function alph8(e:MouseEvent):void
{{n8.alpha = .5;n8.removeEventListener(MouseEvent.MOUSE_DOWN, alph8);};
n9.addEventListener(MouseEvent.MOUSE_DOWN, alph9);
function alph9(e:MouseEvent):void
{{n9.alpha = .5;n9.removeEventListener(MouseEvent.MOUSE_DOWN, alph9);};
{startBtn.visible = true}
Can anyone please help.
Thanks in advance
with best regards

i have copied and pasted the code as given below. Can you please point out
if there is anything that needs to be completed. Or rather, how can i
complete the "if" statement:
var positions:Array = [new Point( 158, 296),new Point(238, 296),new
Point(318,  296),
new Point( 158, 366),new Point( 238, 366),new Point( 318, 366),new
Point(158, 436),
new Point( 238,436),new Point(318, 436)];
var errors:int;
var mcs:Array = ;
startF();
function startF():void{
errors=0;
shuffle(positions);
for(var i:int=0;i<positions.length;i++){
mcs[i].addEventListener(MouseEvent.MOUSE_DOWN,downF);
mcs[i].x=positions[i].x;
mcs[i].y=positions[i].y;
mcs[i].alpha=1;
function downF(e:MouseEvent):void{
if(mcs.indexOf(e.currentTarget)==0 ||
mcs[mcs.indexOf(e.currentTarget)-1].alpha<.8){
e.currentTarget.alpha=.5;
e.currentTarget.removeEventListener(MouseEvent.MOUSE_DOWN,downF);
if(mcs.indexOf(e.currentTarget)==mcs.length-1){
gameoverF();
} else {
errors++;
function gameoverF():void{
// display congrats if errors 0 or some other low number
// when you want to restart the game, call startF().
function shuffle(a:Array) {
    var p:int;
    var t:*;
    var ivar:int;
    for (ivar = a.length-1; ivar>=0; ivar--) {
        p=Math.floor((ivar+1)*Math.random());
        t = a[ivar];
        a[ivar] = a[p];
        a[p] = t;
thanks a lot
