What's wrong with my drag n drop code

Question

Here's the stage of something I'm working on:
When you click on the blue buttons (movieclip buttons I've created with over/down/click states) they expand and play a sound.
This works beautifully.
Here's what I did for each movieclip button:
The idea is the student then drags them to the corresponding IPA symbol target. So, I want to add "drag n drop" functionality. I've copied and ammended some code from a tutorial but can't get it to work - the blue buttons lose their audio and once dragged, cannot be dropped.
Two possibilities - either the same movieclip button cannot have a click audio PLUS drag n drop funcionality or I've done something wrong with the code. Can anyone enlighten me which is the case?
Thanks a lot in advance. I'm new to this and I've come up against a brick wall here.
(Below, in the code, I've disabled line 1 to line 70, the drag n drop part, which doesn't work. The code below line 70 for the audio click buttons works fine on its own)

Answer 1

Yes, they worked fine.
OK, I've simplified all this. I've removed the sounds part from the equation, placing the sounds on simple buttons that don't form part of the drag n drop. They work.
I've now got 3 objects to drag and 3 destinations. Still got the same problem, I can drag but drop doesn't work.
In the original tutorial, the objects had instance names like "flower_mc" and the destinations were "targetflower_mc".
In my example, I've used object instance names like "peg1_mc" and for destinations "targetpeg1_mc" to try and preserve functionality.
EDIT: Other points: In the tutorial, when you drag the object, it drags from the middle. In mine, it drags from top right-hand corner. Is this important? I know it's based on regitration point but I have no idea how to change it in mine.
Here's the new code:
var counter:Number = 0;
var startX:Number;
var startY:Number;
peg1_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
peg1_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);
peg2_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
peg2_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);
peg3_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
peg3_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);
function pickUp(event:MouseEvent):void {
    event.target.startDrag(true);
    reply_txt.text = "";
    event.target.parent.addChild(event.target);
    startX = event.target.x;
    startY = event.target.y;
function dropIt(event:MouseEvent):void {
    event.target.stopDrag();
    var myTargetName:String = "target" + event.target.name;
    var myTarget:DisplayObject = getChildByName(myTargetName);
    if (event.target.dropTarget != null && event.target.dropTarget.parent == myTarget){
        reply_txt.text = "Good Job!";
        event.target.removeEventListener(MouseEvent.MOUSE_DOWN, pickUp);
        event.target.removeEventListener(MouseEvent.MOUSE_UP, dropIt);
        event.target.buttonMode = false;
        event.target.x = myTarget.x;
        event.target.y = myTarget.y;
        counter++;
    } else {
        reply_txt.text = "Try Again!";
        event.target.x = startX;
        event.target.y = startY;
    if(counter == 3){
        reply_txt.text = "Congrats, you're finished!";
peg1_mc.buttonMode = true;
peg2_mc.buttonMode = true;
peg3_mc.buttonMode = true;
