Lua Problem with HOTA Quest

[bivan]

I'm using a Cykotitan script:

local config = {
	ids = {from=2335, to=2341},
	storage = 4449,
	item = 2342
}
function onStepIn(cid, item, position, fromPosition)
	if getPlayerStorageValue(cid, config.storage) < 1 then
		for i = config.ids.from, config.ids.to do
			if getPlayerItemCount(cid, i) < 1 then
				failed = true
				break
			end
		end
		if not failed then
			for i = config.ids.from, config.ids.to do
				doPlayerRemoveItem(cid, i, 1)
			end
			local pos = getCreaturePosition(cid)
			doCreateItem(config.item, 1, {x=pos.x, y=pos.y-1, z=pos.z})
			setPlayerStorageValue(cid, config.storage, 1)
		else
			doPlayerSendCancel(cid, "You don't have all the required items.")
		end
	else
		doPlayerSendTextMessage(cid, MESSAGE_EVENT_ADVANCE, "You already done this quest.")
	end
end

And select uniqueid at the stone tile before altar stone and put all parts of helmet and is nothing happened. Can somebody help me?
