Having trouble with item using skill script

[Clockwise]

I've been trying to use SephirothSpawn's 'Skill Use Item' script
http://www.rmxpu.net/staff/sephirothspawn/Script%20Files/Skills%20Use%20Items.txt
to make healing moves which require that an item be consumed to work.
It seems the 1st bit of the script is working since it understands that I need the item to use the skill, but when I use the skill it doesn't consume an item.

Also I was curious if I wanted multiple skills that each needed to consume there own individual item if I'd just add more Item_Cost lines with different skill numbers and item numbers or if I'd have to add a whole new script for each one.

This is what I have:

*Bump*
Sorry to be a pain with the bump but I'm still having trouble getting this to work.
I've tried adding the SDK script but I had the same problem (and for some odd reason it deleted the fight/escape words when I got into a fight). Though, I have been getting a slight sense of how scripting works by looking up how this script references to other scripts and gives extra conditions and 'equations'. But that pretty much where my scripting knowledge ends for the time being, so I'm having trouble seeing where the small (or large) problem might be thats making it so an item isn't consumed after the skill is used.

I think you need post all the script that actually are in your proyect.
___________________________

Now, for the Items, remember this script requires the SDK, because there is a new version of the script:

#==============================================================================

  Item_Cost = {

  Item_Cost.default = {}

        # Items

          ids.each do |id, n|
            return false if $game_party.item_number(id) < n

        # Lose Item Cost
        skill.item_cost.each do |item_type, ids|

            ids.each { |id, n| $game_party.lose_item(id, n) }
          # Weapons
          elsif item_type == 1
            ids.each { |id, n| $game_party.lose_weapon(id, n) }

            # Lose All Armors

        end
      end
    end
    # Return Effectiveness
    return effective
  end
end

#--------------------------------------------------------------------------
# * End SDK Enable Test
#--------------------------------------------------------------------------
end

Now, go to this Line:

class RPG::Skill
  #--------------------------------------------------------------------------
  # * Skills That Use Items
  #
  #  ~ skill_id => { item_type => { id => n, ... }, ...}
  #
  #  Item_Types = 0 : Items, 1 : Weapons, 2 : Armors
  #--------------------------------------------------------------------------
  Item_Cost = {
  }
  Item_Cost.default = {}

and when says:

 Item_Cost = {
  }

put your requirements.

- Type of the item: The type, 0 : Items, 1 : Weapons, 2 : Armors.
- ID: The ID of the Item (the ID of the item, that is in the Type Database Item)
- N: The ammount of Item that will be used in the Skill.

For example (By default) to use the Skill ID: 1 (Heal) you need Item ID: 1 (Potion) 2x.

 Item_Cost = { 1 => { 0 => {1, 2} } }

Now that will work ( I tested it), but if you have another scripts that affect the Skill or something I don't know, so you need the help of another skilled scripter. but if that work for you Good.

Luck!

Thanks!!
Both requiring and consuming an item are working now but theres still two littler things that I'm having trouble with.

1) The first is that if I heal a character in battle when their health is full the skill still heals them without consuming the item.
So I was wondering if there was a way to either make it so they can't be healed when they have full life or make the the skill consume an item in this situation as well.

2) The other problem I'm having is making it so that more then one skill can require an item. I tried adding an extra item_cost line but it made it so only the second item_cost worked. So then I tried making a second copy of the script but I get a "System Stack Error - stack level too deep" when I go into skills menu.

Thanks again for the help!
