Why tween don't reflect the value in textField.y?

Question

Here are my codes:
function textReady(event:Event):void
    txtFormat.font = weiss.fontName;
    txtFormat.color = 0x000066;
    txtFormat.size = 24;
    //txtField.x = stage.stageWidth;
    //txtField.width = 800;
    txtField.autoSize = TextFieldAutoSize.LEFT;
    //txtField.height = txtField.autoSize
    txtField.wordWrap = false;
    txtField.text = event.target.data;
    txtField.setTextFormat(txtFormat);
    txtField.y = 350;
    txtField.embedFonts = true;
//load external texts
textLoad.load(textRequest);
textLoad.addEventListener(Event.COMPLETE, textReady);
txtField.x = stage.stageWidth;
addChild(txtField);
TweenLite.to(txtField, 30, {x:-stage.stageWidth*2.25, ease:None.easeInOut, delay:0.5, onComplete:myFunction});
function myFunction():void {
    textLoad.load(new URLRequest("inspiration.txt"));
    txtField.x = 150;
    txtField.y = 100;
    txtField.alpha = 0;
    TweenLite.to(txtField, 5, {alpha:1, onComplete:nextText});
    //slideXTween = new Tween(txtField, "alpha", None.easeNone, 0, 1, 70, true);
    //TweenLite.to(txtField, 30, {x:-184, ease:None.easeInOut, delay:0.5, onComplete:nextText});
    //trace("tween finished");
    trace(txtField.y);
function nextText():void{
    trace("tween done");
I did a trace on the txtField.y and it does show 100 in the myFunction. However, when the textLoad appears on the screen, it still appears at y=350. Any idea why this is happening?

Okay, here is my full code:
//import classes
import com.greensock.TweenLite;
import caurina.transitions.*;
import fl.transitions.Tween;
import fl.transitions.easing.*;
//end of importing
//start of sound section is for sound
var soundReq:URLRequest=new URLRequest("PaukenBrumfiel_AngelsOnHigh.mp3");
var sound:Sound = new Sound();
sound.load(soundReq);
sound.addEventListener(Event.COMPLETE, onComplete);
//end of sound section
//Loading external texts
var weiss:Font = new Weiss();
var slideXTween:Tween;
var txtAlphaTween:Tween;
var txtNextText:Tween;
var txtContainer:Sprite;
var txtField:TextField = new TextField();
var textRequest:URLRequest=new URLRequest("happyHoliday.txt");
var textLoad:URLLoader = new URLLoader();
var txtFormat:TextFormat = new TextFormat();
//end of loading external texts
function onComplete(event:Event):void {
    sound.play();
function textReady(event:Event):void
    txtFormat.font = weiss.fontName;
    txtFormat.color = 0x000066;
    txtFormat.size = 24;
    //txtField.x = stage.stageWidth;
    //txtField.width = 800;
    txtField.autoSize = TextFieldAutoSize.LEFT;
    //txtField.height = txtField.autoSize
    txtField.wordWrap = false;
    txtField.text = event.target.data;
    txtField.setTextFormat(txtFormat);
    txtField.y = 350;
    txtField.embedFonts = true;
//load external texts
textLoad.load(textRequest);
textLoad.addEventListener(Event.COMPLETE, textReady);
txtField.x = stage.stageWidth;
addChild(txtField);
trace("First txtField.y: " + txtField.y);
TweenLite.to(txtField, 30, {x:-stage.stageWidth*2.25, ease:None.easeInOut, delay:0.5, onComplete:myFunction});
function myFunction():void {
    trace("Second txtField.y: " + txtField.y);
    textLoad.load(new URLRequest("inspiration.txt"));
    txtField.x = 150;
    txtField.y = 100;
    trace("Third txtField.y: " + txtField.y);
    txtField.alpha = 0;
    TweenLite.to(txtField, 5, {alpha:1, onComplete:nextText});
    //slideXTween = new Tween(txtField, "alpha", None.easeNone, 0, 1, 70, true);
    //TweenLite.to(txtField, 30, {x:-184, ease:None.easeInOut, delay:0.5, onComplete:nextText});
    //trace("tween finished");
    trace("Fourth txtField.y: " + txtField.y);
function nextText():void{
    trace("tween done");
//end of loading external texts
Here are what the traces show:
First txtField.y: 0
Second txtField.y: 350
Third txtField.y: 100
Fourth txt/Field.y: 100
I believed I only have one textfield but again, I'm a beginner in action script.
Thanks for many of your help so far.
