External text issue

Question

I have tried to look up this issue in the flash help,
lynda.com and here with no luck.
I have an issue with external text that I import. The text
loads fine but when I click to go to another frame in the same
timeline the previous text stays and the new text renders over the
previous text. How do I delete the previous text file when I click
to go to another section.
Here is the code that I am using:
stop();
var externalText:TextField = new TextField();
var externalFormat:TextFormat = new TextFormat();
var externalRequest:URLRequest = new
URLRequest("../textFiles/home.txt");
var externalLoad:URLLoader = new URLLoader();
externalLoad.load(externalRequest);
externalLoad.addEventListener(Event.COMPLETE, textReady);
up_Btn.addEventListener(MouseEvent.CLICK, scrollUp);
down_Btn.addEventListener(MouseEvent.CLICK, scrollDown);
externalText.x = 34.6;
externalText.y = 42.1;
externalText.width = 374;
externalText.height = 211;
externalText.border = false;
externalText.wordWrap = true;
externalFormat.font = "Humanst521 BT";
externalFormat.color = 0xffffff;
externalFormat.size = 13;
addChild(externalText);
function textReady(event:Event):void
externalText.text = event.target.data;
externalText.setTextFormat(externalFormat);
function scrollUp(event:MouseEvent):void
externalText.scrollV --;
function scrollDown(event:MouseEvent):void
externalText.scrollV ++;
fuseDrinks_Btn.addEventListener(MouseEvent.CLICK, fdClick);
function fdClick(event:MouseEvent):void
gotoAndPlay("drink");
fuseFood_Btn.addEventListener(MouseEvent.CLICK, ffClick);
function ffClick(event:MouseEvent):void
gotoAndPlay("food");
fuseRes_Btn.addEventListener(MouseEvent.CLICK, frClick);
function frClick(event:MouseEvent):void
gotoAndPlay("rest");
Thanks for any help with this.

if you only change your urlrequest and keep the same
textfield, loader and listener you should have no problem.
otherwise, you're apt to have problems unless you properly account
for those objects you're not re-using.
p.s. unless you embedFonts, you're users are not likely to
see that font.
