Hello Everybody,

I'm creating a NPC from Island of Destiny, but my knowledge is small.

I want create a Knight Hykrion from Island of destiny.

Your transcript is: Hi, yes, knighthood, yes, yes.

I need help to fix this script:

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

function onCreatureAppear(cid)                npcHandler:eek:nCreatureAppear(cid) end
function onCreatureDisappear(cid)            npcHandler:eek:nCreatureDisappear(cid) end
function onCreatureSay(cid, type, msg)            npcHandler:eek:nCreatureSay(cid, type, msg) end
function onThink()                    npcHandler:eek:nThink() end

function creatureSayCallback(cid, type, msg)
    if (msgcontains(msg, "yes") or msgcontains(msg, "YES"))  then
    npcHandler:say("Yes, that's the attitude you need as a knight - strong-willed and determined! I can either you {knighthood} immediately or give you more information about us. What's your wish?", cid)
elseif Topic[cid] == 1 then
        if msgcontains(msg, 'information') or msgcontains(msg, "INFORMATION") then
            npcHandler:say("MESSAGE TO INFORMATION!", cid)
            Topic[cid] = nil
        elseif msgcontains(msg, "no") then
            npcHandler:say("Well, I won't talk you into it. Maybe you would like to hear what {Narai}, {Estrella} and {Yandur} have to say about the other vocations. Ask me about {Information} anytime.", cid)
            Topic[cid] = nil
        end
        if msgcontains(msg, 'knighthood') or msgcontains(msg, "KNIGHTHOOD") then
            npcHandler:say("Are you sure that you can fulfill the duties of a knight and that you have all needed information?", cid)
            Topic[cid] = 2
        elseif msgcontains(msg, "no") then
            npcHandler:say("Well, I won't talk you into it. Maybe you would like to hear what {Narai}, {Estrella} and {Yandur} have to say about the other vocations. Ask me about {Information} anytime.", cid)
            Topic[cid] = nil
        end
elseif Topic[cid] == 2 then
    if msgcontains(msg, 'yes') or msgcontains(msg, "YES") then
            npcHandler:say("Be aware that this decision is final! Step in front of me and annouce it proudly: DO YOU WANT TO BE A KNIGHT?", cid)
            talk_state = 1
            else
            npcHandler:say('MENSAGEM QUE INFORMA O PLAYER QUE JÁ TEM LV!', cid)
            talk_state = 0
            end
            Topic[cid] = 3
        elseif msgcontains(msg, "no") then
            npcHandler:say("Well, I won't talk you into it. Maybe you would like to hear what {Narai}, {Estrella} and {Yandur} have to say about the other vocations. Ask me about {Information} anytime.", cid)
            npcHandler:releaseFocus(cid)
            Topic[cid] = nil
        end

            doPlayerSetVocation(cid, 4)
                        setPlayerStorageValue(cid, 43211,1)
                        doSendMagicEffect(getCreaturePosition(cid), 14)
            else
            npcHandler:say('SE APARECER ESSA MENSAGEM, MANTER.', cid)
            end
        elseif msgcontains(msg, "no") then

        end
    return true
