[TFS 0.4] NPC - Addon per items

[ADMShadow]

Hi guys, I've tried a script but, it just doesn't work whenever I talk to Varkhal.
It shows an error when I say hi to him.

It says it's an error in function onCreatureSay and isInRange


That's my script:

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


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

npcHandler:setMessage(MESSAGE_GREET, "Greetings |PLAYERNAME|. Will you help me? If you do, I'll reward you with nice addons! Just say {addons} or {help} if you don't know what to do.")

function playerBuyAddonNPC(cid, message, keywords, parameters, node)
if(not npcHandler:isFocused(cid)) then
return false
end
if (parameters.confirm ~= true) and (parameters.decline ~= true) then
if(getPlayerPremiumDays(cid) == 0) and (parameters.premium == true) then
npcHandler:say('Sorry, but this addon is only for premium players!', cid)
npcHandler:resetNpc()
return true
end
if (getPlayerStorageValue(cid, parameters.storageID) ~= -1) then
npcHandler:say('You already have this addon!', cid)
npcHandler:resetNpc()
return true
end
local itemsTable = parameters.items
local items_list = ''
if table.maxn(itemsTable) > 0 then
for i = 1, table.maxn(itemsTable) do
local item = itemsTable
items_list = items_list .. item[2] .. ' ' .. getItemNameById(item[1])
if i ~= table.maxn(itemsTable) then
items_list = items_list .. ', '
end
end
end

elseif (parameters.cost > 0) then

elseif table.maxn(parameters.items) then

end

return true
