ca someone help me this: i need to find out how to create a dynamic text box inside the MovieClipLoader so it can be preloaded please anyone …help!

here is my code:
MovieClip.prototype.fadeIn = function() {
this.onEnterFrame = function() {
if (this._alpha<100) {
this._alpha += 10;
} else {
delete this.onEnterFrame;
}
};
};
bar._visible = false;
border._visible = false;
var empty = this.createEmptyMovieClip(“container”, “100”);
empty._x = 0;
empty._y = 0;
my_mc = new MovieClipLoader();//inside this
preload = new Object();
my_mc.addListener(preload);
this.createTextField(“my_txt”, 3, 200, 90, 450, 150);// i need to link this (2 rows up)
my_txt.type=“dynamic”;
my_txt.multiline = true;
my_txt.wordWrap = true;
//my_txt.embedFonts = true;
my_txt.font="_sans";
var my_fmt:TextFormat = new TextFormat();
my_fmt.color = 0xB6C0B6;

preload.onLoadStart = function(targetMC) {
trace("started loading "+targetMC);
container._alpha = 0;
bar._visible = true;
border._visible = true;
pText._visible = true;
};
preload.onLoadProgress = function(targetMC, lBytes, tBytes) {
bar._width = (lBytes/tBytes)*100;
pText.text = “% “+Math.round((lBytes/tBytes)*100);
};
preload.onLoadComplete = function(targetMC) {
container.fadeIn();
border._visible = false;
bar._visible = false;
dText._visible = false;
trace(targetMC+” finished”);
};

loadText = new LoadVars();
loadText.load(“lorem.txt”);
loadText.onLoad = function() {
my_txt.text = this.txtField;
my_txt.setTextFormat(my_fmt);
};
trace(my_txt);
