Need help serius

UPS just forgot to add "if"
DELETE PLEASE
Heyya I coppied and edited fan of knives
and have a code with it to use

function Trig_Death_Cry_Actions takes nothing returns nothing
local unit caster
local real x
local real y
set x = GetUnitX(GetTriggerUnit())
set y = GetUnitY(GetTriggerUnit())
set caster = CreateUnitAtLoc(GetOwningPlayer(GetTriggerUnit()),'h00C',Location(x,y),bj_UNIT_FACING)
call SetUnitAbilityLevel(caster,'A00U',GetUnitAbilityLevel(GetTriggerUnit(),'A00W'))
call IssueImmediateOrderBJ(caster,"fanofknives")
call UnitApplyTimedLife(caster,'BTLF',2)
set caster = null
endfunction

//===========================================================================
function InitTrig_Death_Cry takes nothing returns nothing
    set gg_trg_Death_Cry = CreateTrigger( )
    call TriggerRegisterAnyUnitEventBJ( gg_trg_Death_Cry, EVENT_PLAYER_UNIT_SPELL_EFFECT )
    call TriggerAddAction( gg_trg_Death_Cry, function Trig_Death_Cry_Actions )
endfunction

Anyway It shuts the game with no errors when I cast the spell h00C is a dummy spell caster btw and A00U is ability to cast by dummy caster (its fan of knives based too) and A00W is ability that hero casts

an advice: indenting your code make it more readable
like this:

function a_stupid_function takes integer a_param returns integer
  local integer a_variable
    set a_variable = 2*a_param
    if (a_variable>=16) then
      return a_variable
    endif
    return 0
endfunction
