TextField...I can still see it

1

Hello guys
I’ve got the code below which is the text field with type writer effect. It works pretty fine.
It is on my main time line about 10 frames, then I’ve got another frames labeled which represent other pages but I can still see the text in others pages.
How can I remove the code so I would not be able to see it somewhere else?
Does my English make sense?

function mainFrame():void {



    var mainTxtMc:TimelineLite = new TimelineLite();
    mainTxtMc.insert(TweenMax.fromTo(main_txt.mainFrameBcg, .8, {alpha:0, scaleX:0, scaleY:0},{alpha:1, scaleX:1, scaleY:.09, onComplete:logoMladezShow}));
    mainTxtMc.append(TweenMax.to(main_txt.mainFrameBcg, .8, {scaleY:1, ease:Elastic.easeOut, onComplete:typeWriter}));

    function typeWriter():void {
        var myText:String;
        var counter:int=0;

        var format : TextFormat = new TextFormat();
        format.size=13;
        format.font="Verdana";
        format.bold=true;
        format.color=0x333333;
        format.align="left";

        var textField : TextField = new TextField();
        textField.width=690;
        textField.height=100;
        textField.selectable=false;
        textField.wordWrap=true;
        textField.defaultTextFormat=format;
        //textField.autoSize = TextFieldAutoSize.RIGHT; 
        textField.x=132;
        textField.y=552;
        addChild(textField);

        var textLoader:URLLoader=new URLLoader(new URLRequest("text.txt"));
        textLoader.addEventListener(Event.COMPLETE, function(e:Event){initText(e.target.data);});

        function initText(string:String):void {
            myText=string;
            addEventListener(Event.ENTER_FRAME, writeText);
            //addEventListener(Event.RENDER, writeText);
        }

        function writeText(e:Event):void {
            if (counter<=myText.length) {
                textField.text=myText.substr(0,counter);
                counter++;
            } else {
                removeEventListener(Event.ENTER_FRAME,writeText);
            }
        }
    }

}
