Problem with applying css to external text

I’m trying to apply css to an external text file according to the tutorial found in this site:

Everything works fine, but I notice that just before the text loads, I get a line of code that says: _level0.output (output is the name of my variable for the dynamic text box)

Here’s the AS applied to the frame with the dynamic text box:

var format = new TextField.StyleSheet();
var path = "styles.css";
format.onLoad = function(loaded) {
if (loaded) {
output.styleSheet = format;
myLoadVar = new LoadVars();
myLoadVar.onLoad = function(success) {
if (success == true) {
	output.variable = "content";
	output.htmlText = myLoadVar.content;
} else {
output.text = "Error loading CSS file!";

You can’t see it locally on your computer cuz it loads too quickly, but you can see it if you put it up on a server. Once the files are on your cache you don’t see it anymore and the text loads up right away. It just happens the first time you load the page. It stays up a lot longer for dial-up viewers.

Any ideas why it’s happening? Cuz it doesn’t happen when you load up regular external text. Is there something wrong in the actionscript as it’s applying the css to the text? Any ideas to get rid of it? Cuz it looks weird to first time viewers of a website.
