Loading .css into my .fla file (non-.AS file)

Question

AS3
My .html file loads, but not my .css file.
I want to add the proper code to load a .css file, which is
for my .html file, directly into my .fla file that has the code for
the text area and scrollbar with the .html file loading
successfully.
How do I load the .css file for the .html file the same way-
the .html file loads correctly, but not the .css file?
****Right now, I get the following errors:
1119: Access of possibly undefined property styleSheet
through a reference with static type fl.controls:TextArea.
myTextField.styleSheet = css;
1120: Access of undefined property pageContent.
myTextField.htmlText = pageContent;
when I try this current AS3 code:
//Load CSS Data
var cssLoader:URLLoader = new URLLoader();
var cssRequest:URLRequest = new URLRequest("example.css");
cssLoader.addEventListener(Event.COMPLETE,
cssLoaderComplete);
cssLoader.load(cssRequest);
function cssLoaderComplete(evt:Event):void{
var css:StyleSheet = new StyleSheet();
css.parseCSS(URLLoader(evt.target).data);
myTextField.styleSheet = css;
myTextField.htmlText = pageContent;
//Load HTML Data
function textLoadComplete(event:Event):void
myTextField.htmlText = textLoader.data;
myTextField.editable = false;
var textLoader:URLLoader = new URLLoader();
var textReq:URLRequest = new URLRequest("htmltext.html");
textLoader.load(textReq);
textLoader.addEventListener(Event.COMPLETE,
textLoadComplete);

Okay - thanks.
The really bizarre thing to me is that I got this simple tutorial:
http://www.macloo.com/examples/flash/CSS_in_Flash/css_with_xml.html
I pasted the exact AS onto my stage:
// set up the textfield attributes
myTextField_txt.html = true;
myTextField_txt.wordWrap = true;
myTextField_txt.multiline = true;
myTextField_txt.condenseWhite = true;
// create new style sheet object
var myCSS = new TextField.StyleSheet();
// specify the location of your existing CSS file
var cssURL = "example_2.css";
// load CSS file
myCSS.load(cssURL);
// define onLoad handler
myCSS.onLoad = function(success) {
    if (success) {
        /* if the style sheet loaded without error */
        myTextField_txt.styleSheet = myCSS;
        myTextField_txt.text = "CSS file loaded successfully. You may proceed.";
    } else {
        myTextField_txt.text = "CSS file failed to load!";
//load the XML file
myContent = new XML();
myContent.ignoreWhite = true;
myContent.load("story_example.xml");
myContent.onLoad = function(success) {
    if (success) {
        myTextField_txt.text = myContent;
    } else {
        myTextField_txt.text += "<br /> XML file failed to load!";
Then I  swap out the css file name with what I have - style_dtf.css - and it doesn't error (no output regarding CSS), but it shows ALL the code from the XML file in a big string, with all the tags and everything.
Very weird...
I even pasted the CSS from the example file into the beginning of my CSS file and still same effect.
I do have all my SWFs in a seperate folder, but for now I just duplicated my CSS and XML into both folders.
