Lua Help with NPC Keywords!

[Kayan]

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
        
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 travelNodeVengoth = keywordHandler:addKeyword({'back'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Eu posso te mandar de volta para o {trade quarter} por 50 moedas. Aceita?'})
local travelNodeVengoth = keywordHandler:addKeyword({'yalahar'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Eu posso te mandar de volta para o {trade quarter} por 50 moedas. Aceita?'})
local travelNodeVengoth = keywordHandler:addKeyword({'trade quarter'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Eu posso te mandar de volta para o {trade quarter} por 50 moedas. Aceita?'})
local travelNodeVengoth = keywordHandler:addKeyword({'passage'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Eu posso te mandar de volta para o {trade quarter} por 50 moedas. Aceita?'})


travelNodeVengoth:addChildKeyword({'yes'}, StdModule.travel, {npcHandler = npcHandler, premium = true, level = 0, cost = 50, destination = {x=32837, y=31365, z=7}, msg = 'Okay. Enjoy!' })
travelNodeVengoth:addChildKeyword({'no'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, reset = true, text = 'Come back anytime.'})

npcHandler:addModule(FocusModule:new())

Why this npc doens't work? I dont want repeat, in all node yes and no. I need a short script!
