Syntax Error

[afters]

I keep getting syntax errors when I try to test my script, always at the class definition. The only thing that these classes have in common that is different from others is the use of alias. Anyone know what is causing this?

Content Hidden

Code:

#==============================================================================
# ** Scene_Title
#------------------------------------------------------------------------------
#  This class performs title screen processing.
#==============================================================================

class Scene_Title
  
  alias :afters_message_new_game :command_new_game
  
  def command_new_game
    afters_message_new_game
    $game_message = Game_Message.new
  end
  
end

#==============================================================================
# ** Interpreter
#------------------------------------------------------------------------------
#  This interpreter runs event commands. This class is used within the
#  Game_System class and the Game_Event class.
#==============================================================================

class Interpreter
  
  alias :afters_msg_command_101 :command_101
  
  def command_101
    afters_msg_command_101
    $game_message.event = $game_map.events[@event_id]
  end
  
end

It was actually an error related to constants in another class, oddly enough.
