Lua NPC task

[Matheus Vieira]

0.4
Hello guys, I'm here to ask for a favor.
To start, I have this npc's script, where it gives the player a task to do, like killing some amount of monsters, and it works perfectly, BUT i want something more.
I was trying to do something like: If the player has a specific storage, the npc will give them the task, but if the player do not have the specific storage, the npc will not give the task and will tell the player about it.

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

local talkState = {}
local quest = 11475
local reward = 70000

local markTable = {
--    {markPos = Coordenadas da marcação, markType = Tipo de marcação, markDescription = Descrição da marcação}
    {markPos = {x = , y = , z = }, markType = MAPMARK_SWORD, markDescription = ""}
}



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

function creatureSayCallback(cid, type, msg)
if(not npcHandler:isFocused(cid)) then
        return false
    end
    
    local func_addMark = doPlayerAddMapMark
    if(not func_addMark) then
      func_addMark = doAddMapMark
    end
 
    if(msgcontains(msg, "location")) then
        for mark, x in pairs(markTable) do
            func_addMark(cid, x.markPos, x.markType, x.markDescription ~= nil and x.markDescription or "")
        end
        selfSay("", cid)
    end
local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid

if(not npcHandler:isFocused(cid)) then
    return false
elseif msgcontains(msg, "") and talkState[talkUser] == 1 then
    npcHandler:say("", cid)
    talkState[talkUser] = 2
elseif msgcontains(msg, "") and talkState[talkUser] == 2 then
    if(getPlayerStorageValue(cid,11476) < 4) then               <!--- Here's the storage that the player need to start this quest  --->
    npcHandler:say("", cid)
    setPlayerStorageValue(cid, quest, 2)
    talkState[talkUser] = 0
                 else
                    npcHandler:say('', cid)
                end
elseif msgcontains(msg, "") then
    local str = getPlayerStorageValue(cid, quest)
    if(str < 2) then
        npcHandler:say("", cid)
        talkState[talkUser] = 1
        return true
    elseif(str == 2) then
        npcHandler:say("", cid)
    elseif(str == 3) then
        npcHandler:say("", cid)
        setPlayerStorageValue(cid, quest, 4)
    elseif(str == 4) then
        npcHandler:say("", cid)
    talkState[talkUser] = 0
        
end
    end

return TRUE
end

npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())

But in this order, where i put the getPlayerStorage it does not work, and i don't know why, the npc gives the task anyway and does not appear any error in the console
