Problem with CSS and AS2

programming flash
1

If I paste this in to an empty Flash document, it doesn’t work. Can anyone tell me why. The Publish settings are Flash Player 7 and ActionScript 2.

import TextField.StyleSheet;

var my_styleSheet:StyleSheet = new StyleSheet();

var styleObj:Object = new Object();
styleObj.color = "#cc0000";
styleObj.fontWeight = "bold";
styleObj.fontFamily = "sans-serif";
my_styleSheet.setStyle("headline", styleObj);
delete styleObj;

for (var i in my_styleSheet) {
    trace(i+ ": " + my_styleSheet*)
    
    for (var j in my_styleSheet*) {
        trace("  "+ j + ": " + my_styleSheet*[j]);
        
        for (var k in my_styleSheet*[j]) {
            trace("      "+ k + ": " + my_styleSheet*[j][k]);
        }
    }
}


this.createTextField("news_txt", this.getNextHighestDepth(), 0, 0, 300, 200);
news_txt.wordWrap = true;
news_txt.multiline = true;
news_txt.html = true;

var newsText:String = "<p class='headline'>Description</p> Method; "
    + "starts loading the CSS file into styleSheet. The load operation is asynchronous; "
    + "use the <span class='bold'>TextField.StyleSheet.onLoad</span> "
    + "callback handler to determine when the file has finished loading. "
    + "<span class='important'>The CSS file must reside in exactly the same "
    + "domain as the SWF file that is loading it.</span> For more information about "
    + "restrictions on loading data across domains, see Flash Player security features.";

news_txt.styleSheet = myStyleSheet;
news_txt.htmlText = newsText;
