Targeting mc's

[Robb@exo]

Hey everyone, this one has me really confused, been trying for a few days now. Here's my issue, I have some buttons(dynamic mc's) set up with an ROLL_OVER/ROLL_OUT MouseEvent handler and have put them in an array. No problem there.

var btnArray:Array = [];
for(var i:int = 0; i < 5; i++) {
	var bg:Bg = new Bg();
	bg.width = 173;
	bg.height = 20;
	bg.x = 25;
	bg.y = (22 * i) + 40;
	bg.name = "bg"+i;
	
	container.addChild(bg);
	btnArray.push(bg.name);

    bg.addEventListener(MouseEvent.ROLL_OVER, mOver);
    bg.addEventListener(MouseEvent.ROLL_OUT, mOut);
}
function mOver(e:MouseEvent):void {
    var twIn:Tween = new Tween(e.currentTarget, "alpha", Regular.easeOut, 0.5, 1, .5, true);
    if(legendArray[idNum][0] == 1) {
        TweenMax.to(dtrArray[0], 1, {tint:0x14170C}); 
    }
    if(legendArray[idNum][1] == 1) {
	TweenMax.to(dtrArray[1], 1, {tint:0x89FC01});
    } etc...
}
function mOut(e:MouseEvent):void {
    var twOut:Tween = new Tween(e.currentTarget, "alpha", Regular.easeOut, 1, 0.5, .5, true);
    TweenMax.to(dtrArray[0], 1, {tint:0x14170C});
    TweenMax.to(dtrArray[1], 1, {tint:0x14170C});
    etc...
}

Next, I set up another array to contain some numeric values that will determine if a mc's tint is changed.(0 = doesn't change, 1 = change).

var legArray:Array = [[1,1,1,0,1],[1,1,0,0,1],[1,0,1,1,0],[0,1,1,0,1],[0,1,0,1,1]];

No issue there either. Next, (this is where questions arise), I dynamically set another group of mc's, and positioned them over the button mc's. So basically 5 mc's( Dot ) per row, and pushed them in an array as well.

var dtrArray:Array = [];
for(var c:int = 0; c < legendArray.length; c++) {
	for(var r:int = 0; r < 5; r++) {
		var dtr:Dot = new Dot();
		dtr.x = 150 + (10 * c);
		dtr.y = 50 + (22 * r);
		dtr.name = "dtr" + r;
		addChild(dtr);
		dtrArray.push(dtr.name);
	}
}

The problem is I can't seem to target the dtr mc's (Dot) at all even when they're in an array. Anyone have any strategies I can use to make this concept finally work? I've been able to do it as long as the dot mc's are a child of the button mc's, but I don't want the rollOver/rollOut effects to effect the child, therefore the separation. Please somebody help me!

I hope it's clear.
