Need Easy Script on Use Item

[merfus]

What script should to do?

If player got storage 2100, 3 and when he do Use on item X ID he get storage 2100, 4 and 1000 exp.
When he get other storage than 2100, 3 example 2100, 2 or 2100, 4 he can't do use on item X ID.

can anyone create for me that script?

local storage = 2100
function onUse(cid, item, fromPos, toPos)
if getPlayerStorageValue(cid, storage) >= 0 then
   if getPlayerStorageValue(cid, storage) == 3 then
      setPlayerStorageValue(cid, storage, 4)
      doPlayerAddExperience(cid, 1000)
   else
      return doPlayerSendCancel(cid, "You cannot use this item yet.")
   end
else
   return doPlayerSendCancel(cid, "You cannot use this item.")
end
return true
end
