TextField problem and centering tween problem

[Leftyplayer]

The final idea is: there are multiple movieclips on stage, on keypress, mc1 will scale larger (tween), text will fade in on corner of stage (tween), audio associated with that mc will play ... then text will fade out and mc1 will scale back down to original size.

The problem (highlighted line where I think problem is in code):

1. When I scale the mc, it should end up at center of the stage from it's original location. Right now, it goes off stage first (off top left), THEN scales to center.

2. I'm formatting text in an array first, then trying to have it show up at the same time as the tween function occurs. The formatting works, but it doesn't show up at all when I say "addChild(textField);" at the time the function runs. Ultimately, I have to set this inside a tween to fade in and out, but for now, I'd at least like to make it show up on stage.

Any thoughts?

Code:

var animalNames:String = "Horse, Cow , Sheep";
var animals:Array = animalNames.split(", ");
var total:int = animals.length;
var textField:TextField = new TextField();
var format:TextFormat = new TextFormat();

stage.addEventListener(KeyboardEvent.KEY_DOWN, tweenHorse);

for (var i:int = 0; i < total; i++){
textField.defaultTextFormat = format
format.font = "Verdana";
format.color =0x000000
format.size = 24;
format.bold = true;
textField.autoSize = TextFieldAutoSize.LEFT;
textField.background = true;
textField.backgroundColor = 0xFFFFFF;
textField.text = animals[i]
textField.x = 50*i
//addChild(textField); (this works here)
trace(animals[i]);

}

function tweenHorse():void
{
setChildIndex(h1_mc, 2);
var tweenHorseX:Tween = new Tween(h1_mc,"scaleX", Strong.easeOut,1,3,secs,true);
var tweenHorseY:Tween = new Tween(h1_mc,"scaleY", Strong.easeOut,1,3,secs,true);
var tweenCenterX:Tween = new Tween(h1_mc, "x", Strong.easeOut, 1, stage.stageWidth/2, secs, true);
var tweenCenterY:Tween = new Tween(h1_mc, "y", Strong.easeOut, 1, stage.stageHeight/2, secs, true);

addChild(animals[0]); //but this does NOT work here
trace("hello horse");
}

I also tried
"addChild(textField);"
"addChild(textField[0]);"
"addChild(animals.textField[0]);"
and a few other things that didn't work and probably don't make sense - but I tried LOL.
