How do I drag and drop multiple objects in a mask?

Question

I’ve been working on a flash simulator to show what our night vision product would look like in the dark. I have been successful in making it work with the following code below. Yet I cannot add a "reticle" image (or symbol) to the draggable mask to make it work. Can someone help me with the code? I looked for hours on the internet and I cannot get it to work. I am new to Flash but am starting to learn as much as I can.

Actionscript 3 Code:

img_nv.mask = mask_mc;

mask_mc.buttonMode = true;

mask_mc.addEventListener(MouseEvent.MOUSE_DOWN, dF);

stage.addEventListener(MouseEvent.MOUSE_UP, dropF);

function dF(event:MouseEvent):void{

mask_mc.startDrag();

}

function dropF(event:MouseEvent):void{

mask_mc.stopDrag();

}

use a loop (like enterframe) and update the reticle's position to match mask_mc's position.

mg_nv.mask = mask_mc;

mask_mc.buttonMode = true;

// eg, if you add reticle_mc to the stage in the authoring environment

removeChild(reticle_mc);

mask_mc.addEventListener(MouseEvent.MOUSE_DOWN, dF);

stage.addEventListener(MouseEvent.MOUSE_UP, dropF);

function dF(event:MouseEvent):void{

addChild(reticle_mc);

this.addEventListener(Event.ENTER_FRAME,reticleF);

mask_mc.startDrag();

}

function dropF(event:MouseEvent):void{

removeChild(reticle_mc);

this.removeEventListener(Event.ENTER_FRAME,reticleF);

mask_mc.stopDrag();

}

function reticleF(e:Event):void{

reticle_mc.x=mask_mc.x; // assuming they both have the same reg points (like the center)

reticle_mc.y=mask_mc.y;

}
