How do I use hitTestObject to determine if an instruction is to be executed?

Question

...I think in my last post I was trying something that wasn't possible, or correct...
There are 9 Children. The alpha of evt.target changes on mouse click, and a square is added around the evt.target which overlaps the two neigbouring Children.
The number of Children is then 10, and I am trying to detect whether the next evt.target is overlapped by the square before passing an instruction to change/not change its alpha.
I'm using switch defined by the numChildren. But in 'case 10' below I want to check first if evt.target.hitTestObject(square)) before deciding what the new alpha should be.
var square:Sprite = new Sprite();
function onMusicClick(evt:MouseEvent):void {
switch (musicContainer.numChildren){
case 9 :
evt.target.alpha = i+0.5;
musicContainer.addChildAt(square, 0);
square.graphics.drawRect(0, 0, 130, 117);
square.x = evt.target.x-39;
square.y = evt.target.y;
trace("case 9. Number of Children now@"+musicContainer.numChildren);
trace(square.x, square.y);
break;
case 10 :
trace(evt.target.hitTestObject(square)); // true
trace("case 10. Number of Children still "+musicContainer.numChildren);
evt.target.alpha = i+0.5;
musicContainer.removeChildAt(0);
musicContainer.addChildAt(square, 0);
square.graphics.drawRect(0, 0, 130, 117);
square.x = evt.target.x-39;
square.y = evt.target.y;
trace(square.x, square.y);
break;
default :
trace("none");
break;
Is this the right way to tackle this? And if so, do I need to add a condition if to case 10 (is that even possible)?
Thank you!

Hi kglad,
I've decided to use a new means to Enable only the Child's neighbour now (neighbour on the right-hand side only).
At one point, the next neighbour is visually on the next line, below and to the left, and so the Square hitTestObject wouldn't pick that up without a special case for the Child on the far-right of each line.
So I'm using Switch. My code is long-hand to say the least! But it works and I can use this["n"+String(i)].mouseEnabled=true; to reset the enabled Children.
Before I do any more I'm going to clean up all these lines... but thank very much for showing me how to use the loop to detect hitTestObject – that will come invaluable soon enough!
function onMusicClick(e:Event) {
    e.currentTarget.alpha = 1;
n0.mouseEnabled=false;
n1.mouseEnabled=false;
n2.mouseEnabled=false;
n3.mouseEnabled=false;
n4.mouseEnabled=false;
n5.mouseEnabled=false;
n6.mouseEnabled=false;
n7.mouseEnabled=false;
n8.mouseEnabled=false;
n9.mouseEnabled=false;
n10.mouseEnabled=false;
n11.mouseEnabled=false;
n12.mouseEnabled=false;
switch (e.currentTarget) {
case n1 :
n2.mouseEnabled=true;
break;
case n3 :
n4.mouseEnabled=true;
break;
case n4 :
n5.mouseEnabled=true;
break;
case n5 :
n6.mouseEnabled=true;
break;
case n6 :
n7.mouseEnabled=true;
break;
case n7 :
n8.mouseEnabled=true;
break;
case n8 :
n9.mouseEnabled=true;
break;
case n9 :
n10.mouseEnabled=true;
break;
case n10 :
n11.mouseEnabled=true;
break;
case n11 :
n12.mouseEnabled=true;
break;
case n12:
n13.mouseEnabled=true;
break;
