hola, me gustaria saber ke es lo ke esta mal, porke no me muestra nada?

Código :

var my_fmt:TextFormat = new TextFormat(); 
my_fmt.font = "font"; /* this is the LinkageID not the symbol name. */ 
my_fmt.size = 8; 
this.createTextField("svnews", this.getNextHighestDepth(), 0, 130, 140, 230); 
svnews.setNewTextFormat(my_fmt); 
svnews.embedFonts = true; 
svnews.multiline = true; 
svnews.wordWrap = true; 
svnews.html = true; 
svnews.selectable = false; 
svnews._rotation = -1; 
svnews._alpha = 75; 


// Create a new style sheet and LoadVars object 
var myVars:LoadVars = new LoadVars(); 
var styles = new TextField.StyleSheet(); 
// Location of CSS and text files to load 
var txt_url = "news.htm"; 
var css_url = "news.css"; 
// Load text to display and define onLoad handler 
myVars.load(txt_url); 
myVars.onData = function(content) { 
storyText = content; 
}; 
// Load CSS file and define onLoad handler: 
styles.load(css_url); 
styles.onLoad = function(ok) { 
if (ok) { 
// If the style sheet loaded without error, 
// then assign it to the text object, 
// and assign the HTML text to the text field. 
svnews.styleSheet = styles; 
svnews.text = storyText; 
} 
}


muchas gracias por adelantado!
saludos!
