Help with Custom ABS Status HUD [Resolved!]

[action]

Hello. I was creating a CMS for my game, and wanted to create a window for battle stats such as HP, MP, State, and Equipment. But, testing it out in the map, but errors pop up. I cannot list the errors, but I can show you the script:

#==================
# Battle Info
# For custom Menu
# - Shows status -
#==================
class Window_BattleInfo < Window_Base
  def initialize(x, y)
    super(x, y, 160, 200)
    refresh
  end
  def refresh
    self.contents.clear
    draw_actor_name(0, 8, 8)
    draw_actor_mp(0, 5, 50)
    draw_actor_hp(100, 5, 58)
    draw_actor_state(0, 5, 64)
    for actor in $game_party.members
        x = 4
        y = WLH * (2 + actor.index * 2)
        draw_actor_parameter_change(actor, x, y)
    end
  end
end

If you could help me, that would be great. You would have your name in the credits of my game.
Thank you!

Sorry if I bumped wrong, but the problem is resolved. I did not include the 'actor' in the fixnums of draw_actor_....
