[JASS] Stacking Charges

[VampireHeart]

I got this from a JASS site and im having trouble. Im new to JASS and when i try to enable the script it says: "Stack Charges needs an intilization function named 'InitTrig_Stack_Charges'." I dont know where it gos or how to get it to work...

(heres the script):

function HasItemtype takes unit whichUnit, item this returns item
   local integer i = 0
   local item whichItem = null
   local integer itemType = GetItemTypeId(this)
   if whichUnit != null then
     loop
       exitwhen i > 6
       set whichItem = UnitItemInSlot(whichUnit, i)
       if GetItemTypeId(whichItem) == itemType and whichItem != this then
          return whichItem
       endif
       set i = i + 1
     endloop
   endif
   return null
endfunction

function StackItem takes unit whichHero, item whichItem returns nothing
   local item stack = HasItemtype(whichHero,whichItem)
   local integer itemCharges = GetItemCharges(stack)
   if stack != null and stack != whichItem and itemCharges > 0 then
       call SetItemCharges( stack, itemCharges+ GetItemCharges(whichItem))
       call RemoveItem( whichItem)
   endif
endfunction

that's because you didnt place it in the map header, but instead in a converted trigger, simply you have to add these lines to the bottom of the trigger:

function InitTrig_Stack_Charges takes nothing returns nothing
endfunction

Yes, to elaborate more, here is an example:

function Trig_TT_Actions takes nothing returns nothing
//Actions//
endfunction

//=============--Line of separation--==============================================================
function InitTrig_TT takes nothing returns nothing//Init function//
    set gg_trg_TT = CreateTrigger(  )//Sets the trigger//
    call TriggerAddAction( gg_trg_TT, function Trig_TT_Actions )//Actions function call thingy//
   //Events//
   //Condition function call thingy//
endfunction

That is where all of the initialization modifications go so that you may register events and call the actions & condition functions etc.
