Action Script 3, can someone spot where my code is wrong?

Question

I want to have my characters controlled separately, with 'FireBoy' moving using the left, up and right keys and with 'WaterGirl' moving with the a, w and d keys. However upon editing my code somehow WaterGirl now moves with the right key instead of the d key. Please can someone spot where I have made a mistake and advise me on how to resolve the problem.
My code for main.as is:
package
  import flash.display.Bitmap;
  import flash.display.Sprite;
  import flash.events.Event;
  import flash.events.KeyboardEvent;

My code for Hero.as (FireBoy) is:
package 
  import flash.display.Bitmap;
  import flash.display.Sprite;
  public class Hero extends Sprite
  [Embed(source="../assets/FireBoy.jpg")]
  private static const FireBoy:Class;
  private var FireBoy:Bitmap;
  public var grav:int = 0;
  public var floor:int = 535;
  public function Hero()
  FireBoy = new Hero.FireBoy();
  scaleX = 0.1;
  scaleY = 0.1;
  addChild(FireBoy);
  public function adjust():void
  this.y += grav;
  if(this.y+this.height/2<floor)
  grav++;
  else
  grav = 0;
  this.y = floor - this.height / 2;
  if (this.x - this.width / 2 < 0)
  this.x = this.width / 2;
  if (this.x + this.width / 2 > 800)
  this.x = 800 - this.width / 2;
And finally my code for Female.as (WaterGirl) is:
package 
  import flash.display.Bitmap;
  import flash.display.Sprite;
  * @author Harry
  public class Female extends Sprite
  [Embed(source="../assets/WaterGirl.png")]
  private static const WaterGirl:Class;
  private var WaterGirl:Bitmap;
  public var grav:int = 0;
  public var floor:int = 535;
  public function Female()
  WaterGirl = new Female.WaterGirl();
  scaleX = 0.1;
  scaleY = 0.1;
  addChild(WaterGirl);
  public function adjust2():void
  this.y += grav;
  if(this.y+this.height/2<floor)
  grav++;
  else
  grav = 0;
  this.y = floor - this.height / 2;
  if (this.x - this.width / 2 < 0)
  this.x = this.width / 2;
  if (this.x + this.width / 2 > 800)
  this.x = 800 - this.width / 2;

Answer 1

You should make use of the trace function to troubleshoot your processing.  Put traces in the different movement function conditionals to see which is being used under which circumstances.  You might consider putting the movement code into one function since they all execute when you process a keyboard event anyways.
