[Script Support - SOLVED] Skills that cost HP

I need help with one of modern algebras scripts: Skills that cost HP

#======================================================================
#  Skills with HP Cost
#  Author: modern algebra (rmrk.net)
#  Version: 1.2
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#    Instructions:
#      Set up the database below according to instructions
#======================================================================
# ** RPG::Skill
#======================================================================

class RPG::Skill
  #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
  # * HP Cost   
  #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  def hp_cost
    # Default value for skills with undefined HP cost
    cost, percent = 0, 0
    case @id
    #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~   
    # * Editable Region   
    #-----------------------------------------------------------------------------------------------------------------------   
    #  For each skill to which you want to assign an hp_cost, set it up like so:   
    #      when skill ID   
    #         cost = <the amount of HP that you want to subtract from the user. If the number is     
    #                     negative, then the user of the skill will be healed by that amount>   
    #         percent = <the percentage of max HP you wish to subtract from the user. If negative,   
    #                             then the user of the skill will be healed by that percentage>   
    #   
    #  There are a couple of examples below. Feel free to delete them once you understand   
    #  what is required of you   
    #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#   when %  % = Skill ID in database     
#     cost = 10 # The amount of HP to subtract from user is 10.
#  percent = 20 # The % of maxhp to subtract from user is 20%.
    when 1
      cost = 10
   percent = 0
    percent = percent.to_f / 100
    return cost, percent
  end
end

class Game_Battler
  #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    end
  end
end


Line 95(The last line) is glitched, and the only part I edited was where modern algebra said people could remove (The set up)

Well, you're missing an end right before:

Code: [Select]

    percent = percent.to_f / 100
    return cost, percent


When I said you could delete the examples I certainly didn't mean the end, just the when branches.

Oh...I didn't realize I deleted an end... Thanks for your help even though you said you were to busy with exams... I'll just fix that and delete this topic... 

Just in case it makes you feel nice I'm accually just going to lock the topic so you can see my reply.
