Hello, I have small bug with my script. When I use my item on players, I want see his helmet name that works fine but if players don't equip helmet server give me errors:

[Error - Action Interface]
data/actions/scripts/scouter_system.lua:onUse
Description:
data/lib/050-function.lua:222: attempt to index a boolean value
stack traceback:
  data/lib/050-function.lua:222: in function 'getItemNameById'
  data/actions/scripts/scouter_system.lua:4: in function <data/actions/scr
ipts/scouter_system.lua:1>

Here is my script,

function onUse(cid, item, frompos, item2, topos)
local head = getItemNameById(getPlayerSlotItem(item2.uid, CONST_SLOT_HEAD).itemid)
   if isPlayer(item2.uid) then
     doPlayerPopupFYI(cid, 'Head: '..head..' ')
   else
     doPlayerSendCancel(cid,"Error")
   end 
return true
end

How to do when checked player don't equip helmet script return 'nothink'?

function onUse(cid, item, frompos, item2, topos)
     if isPlayer(item2.uid) then
         local head, helmet = 'None', getPlayerSlotItem(item2.uid, CONST_SLOT_HEAD).itemid
         if helmet > 0 then
             head = getItemNameById(helmet)
         end
         doPlayerPopupFYI(cid, 'Head: '..head..' ')
     else
         doPlayerSendCancel(cid,"Error")
     end
     return true
