*@#% CSS ...

Thanks for the reply Dave/DMennenoh

Well then, here's a specific question.
I cut this code directly from the Adobe sample file named formattedtext.fla
I have a naive expectation, that I could simply change the CSS file name and the TXT file name in this code (of course pointing at a new directory), and the it would just ... WORK! But so far, no succes, and it is ekstremely frustrating (CCS in GoLive is a dream!).
Question is: what needs to be renamed/altered in this code to get it playing right:

//load text
function loadMyText(evt) {
var loadit_lv:LoadVars = new LoadVars();
loadit_lv.load(" http://www.helpexamples.com/flash/text/sampletext.txt");
loadit_lv.onLoad = function(success:Boolean) {
if (success) {
my_txt.text = this.content;
} else {
trace("Could not load text file.");
}
};
}
loadMyText();

//apply stylesheet
var flash_css = new TextField.StyleSheet();
flash_css.load(" http://www.helpexamples.com/flash/text/styles.css");
flash_css.onLoad = function(success:Boolean) {
if (success) {
my_txt.styleSheet = flash_css;
} else {
trace("Could not load CSS file.");
}
};
