Absorb shield spell gives wrong values

[Kazuga]

Edit:
Problem solved, the unit was healed more than it should because I forgot to destroy the trigger when the shield goes down. It ran 2 times and 3 times etc for each spell cast on myself.

Ok so for the first time I'm making my own absorbing shield from scratch in vJass, but I bumped into a problem. When I use the spell on myself I receive the buff and everything, the trigger displays that the amount of shield power loss on every hit so far so good. But the "healing" part bugs, I need to "heal" the unit with the same amount of damage as he takes so it stays the same for as long as he has the absorbing shield.

Now for some reason he receives too much health, it looks more like he is being healed the actual amount of damage he takes, if you know what I mean...

(Btw, don't mind that I actually use a global here, the spell is supposed to be MPI not MUI.)

scope AbsorbShield initializer Lightning
//! runtextmacro HAIL_CreateProperty ("Data", "integer", "private")

globals
private constant integer raw           = 'A00B'  
private constant integer damage        = 200    
endglobals

globals
real array SP [13] //ShieldPower
endglobals

private function Conditions takes nothing returns boolean
return GetSpellAbilityId() == raw
endfunction

private function Absorb takes nothing returns nothing
    local trigger trg = GetTriggeringTrigger()
    local unit Unit = GetTriggerUnit()
    local integer I = GetConvertedPlayerId(GetOwningPlayer(Unit))
    local real DT = GetEventDamage()
    local real CH = GetUnitState(Unit,UNIT_STATE_LIFE)
    
    call BJDebugMsg("c")
    if UnitHasBuffBJ(Unit,'B003') == true then
        call SetUnitState(Unit,UNIT_STATE_LIFE,CH+DT)
        set SP<i> = SP<i> - DT
        call BJDebugMsg(R2S(SP<i>))
        if SP<i> &lt; 0 then
            call UnitRemoveBuffBJ(&#039;B003&#039;,Unit)
            set CH = GetUnitState(Unit,UNIT_STATE_LIFE)
            call SetUnitState(Unit,UNIT_STATE_LIFE,CH-SP<i>)
        endif
    endif
    
    set Unit = null
endfunction

private function Actions takes nothing returns nothing
    local unit Unit = GetSpellTargetUnit()
    local integer I = GetConvertedPlayerId(GetOwningPlayer(Unit))
    local trigger trg = CreateTrigger()
    local triggeraction ta
    
    call TriggerRegisterUnitEvent( trg, Unit, EVENT_UNIT_DAMAGED )
    set ta = TriggerAddAction( trg, function Absorb )
    call BJDebugMsg(&quot;j&quot;)
    set SP<i> = damage
endfunction

//===========================================================================
private function SafeFilt takes nothing returns boolean
return true
endfunction

private function Lightning takes nothing returns nothing
    local trigger trig = CreateTrigger()
    
    call TriggerRegisterPlayerUnitEvent(trig,GetLocalPlayer(),EVENT_PLAYER_UNIT_SPELL_EFFECT,Condition(function SafeFilt))
    call TriggerAddCondition (trig, Condition (function Conditions ) )
    call TriggerAddAction (trig, function Actions )
 endfunction

endscope</i></i></i></i></i></i>

It should just be to set the units life the it's current life + the damage taken right? Or am I thinking wrong?
