How to display buttons on the stage?

[harte93]

I'm having an issue with an upbutton not appearing after I compile my program, and I have no idea why it won't show up. The character png. file shows up fine. Please let me know you have any ideas. I've attached a screen shot (blurred some parts of it) and included the code. 

package

{

          import flash.display.Loader;

          import flash.display.Sprite;

          import flash.events.MouseEvent;

          import flash.net.URLRequest;

          [ SWF(width="550", height="400",

    backgroundColor="#FFFFFF", frameRate="60") ]

          public class GameWorld1 extends Sprite

          {

  // define variables for background

                    public var backgroundURL:URLRequest;

                    public var backgroundLoader:Loader;

                    public var background:Sprite;

  // declare variables for character

                    public var characterURL:URLRequest

                    public var characterLoader:Loader;

                    public var character:Sprite;

  // declare variables for up button

                    public var upButtonURL:URLRequest;

                    public var upButtonLoader:Loader;

                    public var upButton:Sprite;

                    public function GameWorld1()

                    {

  //upload background to stage

                              backgroundURL = new URLRequest();

                              backgroundLoader = new Loader();

                              background = new Sprite();

                              backgroundURL.url = "../images/background.png";

                              backgroundLoader.load(backgroundURL);

                              background.addChild(backgroundLoader);

                              stage.addChild(background); 

  //upload character to stage

                              characterURL = new URLRequest();

                              characterLoader = new Loader();

                              character = new Sprite();

                              characterURL.url = "../images/johnny.png";

                              characterLoader.load(characterURL);

                              character.addChild(characterLoader);

                              stage.addChild(character);

                              character.x = 275;

                              character.y = 150;

  //upload upButton to stage

                              upButtonURL = new URLRequest();

                              upButtonLoader = new Loader();

                              upButton = new Sprite();

                              upButtonURL.url = "../images/up.png";

                              upButtonLoader.load(upButtonURL);

                              stage.addChild(upButton);

                              upButton.x = 25;

                              upButton.y = 25;

                    }

          }

}

there is no line of:

upButton.addChild(upButtonLoader);
