external font need help

[kofa]

hello all



I'm trying to use an external font in flash
I used the Html txt method

The code works in html file

code:

<style type="text/css">p{color:red;text-align:center;font-family: "kofa";font-size: 50px;}@font-face {font-family: "kofa";src: url(kofa.ttf) format("truetype");}</style><p>hello world</p> 

But it doesn't work in flash

code:

onFrame (1) {
    stop();
//---------------- simple text works fine -------------------------    
    this.createTextField("simple_txt", this.getNextHighestDepth(),0,30,200,50);
    simple_txt.html = true;
    simple_txt.htmlText = "<b> this is simple text </b>";

//---------------- external font text is not working --------------------

    this.createTextField("external_font", this.getNextHighestDepth(),0,90,200,50); 
    external_font.html = true;     
    external_font.htmlText='<style type="text/css">p{color:red;text-align:center;font-family: "kofa";font-size: 50px;}@font-face {font-family: "kofa";src: url(kofa.ttf) format("truetype");}</style><p>hello world</p>' 
     
} 

Any Help
