Help - creating Hyperlink in externally loaded .txt file

Hi,
I have a movieclip with a dynamic text field that externally loads a .txt file

var externalReq:URLRequest = new URLRequest("text_news.txt");
var externalLoad:URLLoader = new URLLoader();
externalLoad.load(externalReq);
externalLoad.addEventListener(Event.COMPLETE, textReady);

as such.

My problem is that this text field will not allow links to be clickable. My dynamic text box in the mc is html enabled. I have tested this code:

Go to <A HREF=“http://www.macromedia.com” TARGET=“frame_Name”>Macromedia’s website</A>

but that doesnt show up in HTML! why., ;/

any suggestions???

thanks!!
xx
