Adding Sprites and scrolling them

[billiondegreedr]

Hi all,
I just started learning AS3 I was just trying out something.To read values from xml and make a drop down menu. I reached only this far

import flash.display.Sprite;
import flash.text.TextField;
import flash.events.MouseEvent;

var i:Number = 0;
var sp:Sprite = new Sprite();
var sptxt:TextField = new TextField();
stage.addEventListener(MouseEvent.MOUSE_DOWN,addMore);

function addMore(e:MouseEvent):void {
    sp.name = "sp"+i;
    sptxt.name = "sptxt"+i;
    this.y+=10;
    //sptxt.addEventListener(MouseEvent.CLICK,EditMe);
    sptxt.text="this is the "+i+"th text";
    addChild(sp);
    sp.addChild(sptxt);
    trace("sp="+sp.name);
    trace("sptxt="+sptxt.name);
    trace("i="+i);
    i++;
}
/*
function EditMe():void {
    sp.sptxt.type=TextFieldType.input();
}
*/

What I did is that,When you click on the stage It will add a new spirte, sp with name sp0,sp1 ... and adds sptxt0,sptxt1... inside sp0,sp1... respectively.I put

this.y+=10;

so that each sp will come along down like a drop down.

And

EditMe()

is a function to make the text field in sp editable.Like if i click sp0,its text,ie sp0.sptxt0 must become editable.But its not working,am getting error as Access to undefined property

Another problem is that am getting output as "this is 0th text" then when i click again,it erases all things and adds "this is 1th text" at y+=0.Its not showing "this is 0th text" above that line. ...

Please help.

Btw One more thing.I think I know how to read XML values into those sptxt0,sptxt1 etc,but how can i make them scroll? Using the Scroll() on sp? or another container is needed?
