How to addChild from an array of MC's based on e.target?

[llyfre]

I have an array of 8 movie clips which can be dragged and dropped onto an MC that is their common hitObject.

I would like whichever mc is being dragged to be added as the child of the hitObject MC when it is dropped, however I am having troubles setting up the code.

Currently, I can only have one specific instance added as a child of the hitObject MC because I don't know what to write inside the addChild() parameter aside from a specific instance name (neither "e.target" nor the array name are acceptable).

Here's my code --any and all help will be most appreciated:

var redArray:Array = [red,red1,red2,red3,red4,red5,red6,red7];

redArray.forEach(setupDrag);
function setupDrag(dragger:MovieClip, index:int, array:Array):void {
    dragger.addEventListener(MouseEvent.MOUSE_DOWN, dragRed);
	dragger.buttonMode=true;}
	
redArray.forEach(setupDrop);
function setupDrop(dropper:MovieClip, index:int, array:Array):void {
    dropper.addEventListener(MouseEvent.MOUSE_UP, dropRed);
	dropper.buttonMode=true;}

function dragRed(e:Event):void{
		e.target.startDrag();}

function dropRed(e:Event):void{
		e.target.stopDrag();
		if (e.target.hitTestObject(drawer_mc))
		{
		drawer_mc.addChild(red1); // THIS LINE IS MY PROBLEM --WHAT TO REPLACE red1 WITH?
		red1.y=10;
		}
}

Thanks in advance!
