Using stylesheet in dynamix text from external .txt

Hello everybody! Thanx alot for all your tips. I have a problem that i cant find in tutorial or forum.

I am loading external textfiles into my *.swf in a dynamic-textfield and want to use CCS to shape them up. Can anyone please help where to put in the stylesheet code to get this working?

var thumb_spacing = 110;
var columns = 5;
// load variables object to handle loading of text
var description_lv = new LoadVars();
description_lv.onData = function(raw_text) {
description_txt.text = raw_text
};
function GeneratePortfolio(portfolio_xml) {
var portfolioPictures = portfolio_xml.firstChild.childNodes;
for (var i = 0; i<portfolioPictures.length; i++) {
var currentPicture = portfolioPictures*;
var currentThumb_mc = menu_mc.createEmptyMovieClip(“thumbnail_mc”+i, i);
currentThumb_mc._x = (i%columns)*thumb_spacing;
currentThumb_mc._y = Math.floor(i/columns)*thumb_spacing;
currentThumb_mc.createEmptyMovieClip(“thumb_container”, 0);
currentThumb_mc.thumb_container.loadMovie(currentPicture.attributes.thumb);
currentThumb_mc.title = currentPicture.attributes.title;
currentThumb_mc.image = currentPicture.attributes.image;
currentThumb_mc.description = currentPicture.attributes.description;
currentThumb_mc.onRollOver = currentThumb_mc.onDragOver=function () {
info_txt.text = this.title;
};
currentThumb_mc.onRollOut = currentThumb_mc.onDragOut=function () {
info_txt.text = “”;
};
currentThumb_mc.onRelease = function() {
image_mc.loadMovie(this.image);
description_lv.load(this.description);
timeline.loadVariables(baseurl + this.TEXT);

    };
}

}
// xml object for xml content (defines sources for selections)
var portfolio_xml = new XML();
portfolio_xml.ignoreWhite = true;
portfolio_xml.onLoad = function(success) {
if (success) {
GeneratePortfolio(this);
} else {
trace(“Error loading XML file”);
}
// no success? trace error (wont be seen on web)
};
// load
portfolio_xml.load(“portfolio.xml”);
