Solved Noob LUA Question about Shop NPC :) tfs 0.3.6 [solved]

[Candlejack]

Basically I don't want the player to be able to trade with an NPC unless this storage variable is set to 1.

This isn't working! Any thoughts? Thank you!

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
local talkState = {}
local storage = 5556

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()


local function creatureSayCallback(cid, type, msg)
    if msgcontains(msg, "trade") then
    if getPlayerStorageValue(cid, storage) == 1 then
      
        npcHandler:addModule(shopModule)

        shopModule:addBuyableItem({'scythe'}, 2550, 800, 1, 'scythe')

        shopModule:addSellableItem({'gram of heroin', 'gram of heroin'}, 5886, 500, 'gram of heroin')
        shopModule:addSellableItem({'gram of weed', 'gram of weed'}, 10608, 175, 'gram of weed')
        shopModule:addSellableItem({'cocaine', 'cocaine'}, 4849, 400, 'cocaine')


        npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
        npcHandler:addModule(FocusModule:new())
    else
        npcHandler:say("Sorry, You're not allowed to use this shop.", cid)
    end
    end
end
