actionscript dynamic text

I have a text box set up in my project and it works fine when I test it but when I put it in the web page it only shows part of the text

here is the setup

and when I build it I get this

i've tried using both embedding and using device font without success anyone have an idea what I might be doing wrong ?

EDIT here are the only calls to text box in acitonscript

function onLoaded(e:Event):void{
    try{
        //try to stuff
    } catch(error:TypeError) {
        error_txt.text = error.toString();
    }
}

    function ioError(e:IOErrorEvent):void {

        error_txt.text = e.text;    
    }

What is the code you are using for setting the text? Since in the actual page 'Error #2124' is centered over the loading symbol, it looks to me like either that is the only text that actually ends up in error_txt OR the dynamic text's width and height are being changed so that 'Error #2124' is all that fits.

Quick guess, set the line behavior type to multiline
