New and need help - drag and drop with dynamic text

Question

So I'm doing this project and as an animator I'm not familiar with the whole action script side of flash
Okay so far I've managed to create the whole Drag and Drop feature and it works well, the thing is I want to make it so when you drag in object in the correct spot and new text appears, and I need like six different object with the dynamic text. but I have no idea how to integrated it in my code or where I should start!
So i based myself on some tutorial so theres some code in there that had dynamic text, but not exactly what i wanted
Your help would be much appreciated!
This is my code:
var counter:Number = 0;
var startX:Number;
var startY:Number;
six_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
six_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);
five_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
five_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);
four_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
four_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);
three_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
three_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);
two_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
two_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);
one_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
one_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;
} else {
reply_txt.text = "Try Again!";
event.target.x = startX;
event.target.y = startY;
    if(counter == 6){
        reply_txt.text = "Congrats, you're finished!";
six_mc.buttonMode = true;
five_mc.buttonMode = true;
four_mc.buttonMode = true;
three_mc.buttonMode = true;
two_mc.buttonMode = true;
one_mc.buttonMode = true;

Answer 1

where you have
xxx.text = ....
is where you're assigning text.
