Lua problem with script

[straher]

This script should set players skulls depending on how many frags they get (storage) but well... it doesn't no problems printed in console when reloading creaturescripts.

function onKill(cid, target, lastHit)
	if cid ~= target and isPlayer(target) then
if(getPlayerStorageValue(cid, 20233) > 1) and getCreatureStorage(cid, 6001) == -1 then
		setPlayerStorageValue(cid, 6001, 1)
		doCreatureSetSkullType(cid, 1) 

	elseif(getPlayerStorageValue(cid, 20233) > 20) and getCreatureStorage(cid, 6002) == -1 then
		setPlayerStorageValue(cid, 6002, 1)
		doCreatureSetSkullType(cid, 2) -- 3 is red

	elseif(getPlayerStorageValue(cid, 20233) > 50) and getCreatureStorage(cid, 6003) == -1 then
		setPlayerStorageValue(cid, 6003, 1)
		doCreatureSetSkullType(cid, 3) -- 5 is black
 
	elseif(getPlayerStorageValue(cid, 20233) > 100) and getCreatureStorage(cid, 6005) == -1 then
		setPlayerStorageValue(cid, 6005, 1)
doCreatureSetSkullType(cid, 4)

	elseif(getPlayerStorageValue(cid, 20233) > 150) and getCreatureStorage(cid, 6006) == -1 then
		setPlayerStorageValue(cid, 6006, 1)
	doCreatureSetSkullType(cid, 5)
end
end
	return true
end
