Problem with npc script

[Darqneez]

I'd like to make my own npc, which would buy some items, and I made a script for this, but it doesnt work. Can someone help me to solve it? here's script:

<?xml version="1.0" encoding="UTF-8"?>
<npc name="Kowal" script="kowal.lua" walkinterval="2000" floorchange="0">
<health now="100" max="100"/>
<look type="131" head="0" body="114" legs="114" feet="0" addons="3"/>
<parameters>
<parameter key="message_greet" value="Witaj |PLAYERNAME|, Masz moze towary, ktore mnie interesuja?" />
</parameters>
</npc>

and Lua:

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
local talkState = {}

function onCreatureAppear(cid) npcHandlernCreatureAppear(cid) end
function onCreatureDisappear(cid) npcHandlernCreatureDisappear(cid) end
function onCreatureSay(cid, type, msg) npcHandlernCreatureSay(cid, type, msg) end
function onThink() npcHandlernThink() end

local shopModule = ShopModule:new()
npcHandler:addModule(shopModule)

shopModule:addSellableItem({''}, 2463, 1000, 'devil helmet')

ok cykotitan, thanks but I don't understand 1 thing. I'd like to make a very similar npc script to this. Only items has changed, I've pasted your script and only changed the names of items their ids etc. But it doesn't work... I don't get it, I've tried many ways to solve this problem, but I just can't repair this, here's code:

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)

function onCreatureAppear(cid) npcHandler:onCreatureAppear(cid) end
function onCreatureDisappear(cid) npcHandler:onCreatureDisappear(cid) end
function onCreatureSay(cid, type, msg) npcHandler:onCreatureSay(cid, type, msg) end
function onThink() npcHandler:onThink() end

local shopModule = ShopModule:new()
npcHandler:addModule(shopModule)

shopModule:addSellableItem({'platinum amulet'}, 2171, 2500, 'platinum amulet')
shopModule:addSellableItem({'amulet of loss'}, 2173, 45000, 'amulet of loss')
shopModule:addSellableItem({'demonbone amulet'}, 2136, 32000, 'demonbone amulet')
shopModule:addSellableItem({'magma amulet'}, 7890, 1500, 'magma amulet')
shopModule:addSellableItem({'glacier amulet'}, 7888, 1500, 'glacier amulet')
shopModule:addSellableItem({'lightning pendant'}, 7889, 1500, 'lightning pendant')
shopModule:addSellableItem({'terra amulet'}, 7887, 1500, 'terra amulet')

shopModule:addSellableItem({'ring of the sky'}, 2123, 30000, 'ring of the sky')
shopModule:addSellableItem({'death ring'}, 6301, 1000, 'death ring')

shopModule:addBuyableItem({'amulet of loss'}, 2173, 50000, 'amulet of loss')
shopModule:addBuyableItem({'stealth ring'}, 2165, 5000, 'stealth ring')
shopModule:addBuyableItem({'time ring'}, 2169, 2000, 'time ring')
shopModule:addBuyableItem({'wedding ring'}, 2121, 50000, 'wedding ring')
shopModule:addBuyableItem({'gold ingot'}, 9971, 5000, 'gold ingot')

npcHandler:addModule(FocusModule:new())
