Does anybody see what I'm doing wrong?  I'm new to the coding part of flash which I guess means I'm still pretty new to Flash.  Thanks in advance for any help.

I recieved the repeating errors:

Code:

import flash.display.MovieClip;

          import flash.events.*;

          import flash.net.*;

          import fl.video.*;

          public class DD3 extends MovieClip

          {

                    //boolean to track whether the trailer is playing (for buttons) and/or producing sound

                    private var isPlaying:Boolean = false;

                    private var isMuted:Boolean = false;

                    //attributes

                    //constructor

                    public function DD3()

                    {

                              //stops all animations (besides the background)

                              trailer.stop();

                              board.stop();

                              board.player.stop();

                              board.muter.stop();

                              Lightningflash.stop();

                              //sets the movie controls to function as buttons

                              board.player.mouseEnabled = true;

                              board.player.buttonMode = true;

                              board.muter.mouseEnabled = true;

                              board.muter.buttonMode = true;

                              //adds appropriate event listeners

                              board.docButton.addEventListener(MouseEvent.MOUSE_UP, gotoDoc);

                    }

                    //event function for the "documentation" button

                    public function gotoDoc(e:MouseEvent):void

                    {

                              //makes the trailer "disappear"

                              trailer.stop();

                              trailer.visible = false;

                              seeker.visible = false;

                              isPlaying = false;

                              //shoot some lightning from the background

                              Lightningflash.gotoAndPlay("lightning");

                              //navigates to the billboard's "documentation" frame and resets event listeners

                              board.gotoAndStop("Doc");

                              board.bkButton.addEventListener(MouseEvent.MOUSE_UP, goBack);

                              board.docScroll.update();

                    }

The rest of the code are mostly repeating but I am missing something. I know I need to define the Lightningflash but how?
