UEEEE displayed instead of text

Question

Hi, I'm learning how to program from a book I purchased and i'm making a simple guessing game. The programming is as follows...
package
          import flash.display.MovieClip;
          import flash.events.MouseEvent;
          public class Main extends MovieClip
                    var startMessage:String;
                    var mysteryNumber:uint;
                    public function Main()
                              init();
                    function init():void
                              //initialize variables
                              startMessage = "I'm thinking of a number between 1 and 100";
                              mysteryNumber = 50;
                              //initialize text fields
                              output.text = startMessage;
                              input.text = "";
                              input.backgroundColor = 0xFFCCCCCC;
                              input.restrict = "0-9";
                              stage.focus = input;
the problem is whenever I test it. I get no errors. In the text box (instance named "output") instead of saying, "I'm thinking of a number between 1 and 100" it is saying "UEEEE". I ran it with debuging permited and it told me I should embed the text or use device central however, the book says not to though.

Answer 1

embed your text and add no text to output in the ide.  only assign text with actionscript unless you use a static textfield.
(and, get a new book if it really adises against embedding fonts.)
