Here is my quest npc

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
local talkState = {}
 
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 talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid
	

if msgcontains(msg, 'backpack') then


	if getPlayerItemCount(cid, 3960) == 1 then
	if getPlayerStorageValue(cid, 20002) == 2 then
			doPlayerRemoveItem(cid, 3960, 1)
			doPlayerAddItem(cid, 2687, 10)
			doPlayerSetStorageValue(cid, 20002, 3)
			talkState[talkUser] = 1

		elseif getPlayerStorageValue(cid, storage) == 1 then
			doPlayerSendCancel(cid, "You do not have my backpack!")
		
		elseif getPlayerStorageValue(cid, storage) == 3 then
			doPlayerSendCancel(cid, "You have already traded this item.")
		
		end
		else doPlayerSendCancel(cid, "You do not have my backpack!")
	end
end
return true
end	

npcHandler:addModule(FocusModule:new())

for some reason he does not reply to the word backpack, what is wrong with him?
