text bold & rotation

[gordonart]

I am trying to make this imported text bold but it does not work:
I also want to rotate the text but when I do the text could not be seen.

Here the code I am working on:

/////
var my_fmt:TextFormat = new TextFormat();
my_fmt.bold = true;
//////
this.createTextField("my_txt", 10, 10, 10, 80, 100);
my_txt.setNewTextFormat(new TextFormat("Arial",12,0xCC6600));
my_txt.autoSize = "left";
my_txt.border = false;
my_txt.multiline = true;
my_txt.wordWrap = true;
my_txt._height = 100;
my_txt._rotation = 0;
my_txt.setTextFormat(my_fmt);

var lorem_lv:LoadVars = new LoadVars();
lorem_lv.onData = function (src:String):Void {
    if (src != undefined) {
        my_txt.text = src;
    } else {
        my_txt.text = "Unable to load external file.";
    }
}

lorem_lv.load("skylt1.txt");
