Font embeding in flash CS5

1

hello

Am trying to use 4 dynamic textfields in a Movieclip in flash cs5.2 of them are helveticaworld bold and other 2 are helveticaworld regular. I have embeded the 2 fonts and export foe Actionscript 3.0. But i can’t get the correct font. it doesn’t have bold.


Font.registerFont(Font1);
            Font.registerFont(Font2);
            
            var format:TextFormat = new TextFormat();
            format.font = "Arial";
            format.bold = true;
            format.size = 18;
            content_mc.name_txt.embedFonts = true;
            content_mc.name_txt.antiAliasType = AntiAliasType.ADVANCED;
            content_mc.name_txt.setTextFormat(format);

i have tried this code in one text field but the Bold is not working…

please hellp me
