Trigger Help

[thef1titan]

Ok, im new to Jass and i've run in to a problem
Im trying to make a trigger where if the spell target's life is 1/6 of max or less then will change to the triggering units player and be moved to a storage area. Also to work it requires an item in item slot 1,2 or 3 and replaces it with an item that smmons the unit.

function SpellChk1 takes nothing returns boolean
    if( not( GetSpellAbilityId() == 'A000')) then
        return false
    endif
        return true
endfunction

function CaptureChkS1 takes nothing returns boolean
    if ( not( GetItemTypeId( UnitItemInSlotBJ( GetTriggerUnit(), 1)) == 'I001')) then
        return false
    endif
        return true
endfunction

function CaptureChkS2 takes nothing returns boolean
    if ( not( GetItemTypeId( UnitItemInSlotBJ( GetTriggerUnit(), 2)) == 'I001')) then
        return false
    endif
        return true
endfunction

function CaptureChkS3 takes nothing returns boolean
    if ( not( GetItemTypeId( UnitItemInSlotBJ( GetTriggerUnit(), 3)) == 'I001')) then
        return false
    endif
        return true
endfunction

function Rate takes nothing returns boolean
    if ( not( R2I(GetUnitStateSwap(UNIT_STATE_LIFE, GetSpellTargetUnit())) <= (R2I(GetUnitStateSwap(UNIT_STATE_MAX_LIFE, GetSpellTargetUnit())) * (1/6)))) then
        return false
    endif
        return true
endfunction

function Red2 takes nothing returns boolean
    if (not(GetOwningPlayer(GetTriggerUnit()) == Player(0))) then               
        return false
    endif
        return true
endfunction

        endif
    endif            
endfunction

//Trigger

function InitTrig_RegCapt takes nothing returns nothing
    set gg_trg_RegCapt = CreateTrigger (  )
    call TriggerRegisterAnyUnitEventBJ(gg_trg_RegCapt, EVENT_PLAYER_UNIT_SPELL_CAST)
    call TriggerAddCondition( gg_trg_RegCapt, Condition(function SpellChk1))
    call TriggerAddAction(gg_trg_RegCapt, function CaptureS1)
endfunction

On a side note: How can i change attack types, like instead of Normal, its fire? Same with armor. (I HAVE looked around, couldnt find it)
