Professional :: Make A Scrolling News Section With A Stage Of 200 W X 250 L?

I am in the process of building a web site and am running into an issue with dynamic loading text.I am trying to make a scrolling news section with a stage of 200 W x 250 LCreated a movie clip with the following coding:

var myTextLoader:URLLoader = new URLLoader();var myTextField_txt:TextField = new TextField();myTextField_txt.wordWrap=true;
myTextLoader.addEventListener(Event.COMPLETE, onLoaded);
function onLoaded(e:Event):void {myTextField_txt.text = e.target.data;addChild(myTextField_txt);} 
myTextLoader.load(new URLRequest("myText.txt"));
 
Then set the clip (which is 250 W x 600 L) on the main stage, moving upwards, creating the auto scroll effect.The problem I am running into is that I can't figure out how to make the text use the whole width of the text box I created. It only uses half of the width, creating columbs like this:
 
Hello and
welcome
to our new

[code]...
 
The text box itself is at least twice the width of the sentences, but they aren't using the full width.
