NPC not functioning..

[Hybery]

Okay I am running an 8.0 Kummerack (edited Evolutions) server..
I have a problem with my NPC that is supposed to sell manarunes and uhs.
He greets me, tells me the offers but when someone types "buy second manarune"
etc he doesnt say anything, charge anything or give anything.
Codes:

<npc name="Rune seller" script="data/npc/scripts/Rune seller.lua" autowalk="25" floorchange="0" access="5" level="1" maglevel="1">
	<health now="150" max="150"/>
	<look type="266" head="114" body="113" legs="113" feet="113" corpse="2212"/>
	<parameters>
		<parameter key="module_shop" value="1" />
		<parameter key="message_greet" value="Hello |PLAYERNAME|. Second and third manarune and UH. Second cost 200CC and third 400CC." />
		<parameter key="shop_buyable" value="second manarune,2281,2000000;second uh,2275,2000000;third manarune,2284,4000000;third uh,2276,4000000" />	
		</parameters>
</npc>

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

-- OTServ event handling functions start
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
-- OTServ event handling functions end

npcHandler:addModule(FocusModule:new())

Thank you!

Are the other manarunes and uh's buyable?
