Solved Help with boat npc

Hello, I can't get the

sail = 1

command to work in this script (inside the last elseif)
Any thoughts on how to set sail=1, not sure why it doesn't work.

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 onPlayerEndTrade(cid)              npcHandler:onPlayerEndTrade(cid) end
function onPlayerCloseChannel(cid)          npcHandler:onPlayerCloseChannel(cid) end
function onThink()                          npcHandler:onThink() end

function creatureSayCallback(cid, type, msg)

local newPosition = {x=95, y=117, z=7}
local cost = 50
local sail = 0
local player = Player(cid)
local oldPosition = player:getPosition()

    if (msgcontains(msg, "hello") or msgcontains(msg, "hi")) and (not npcHandler:isFocused(cid)) then
        npcHandler:say('Hello there ' .. getPlayerName(cid) .. ', I only {sail} to Lake Arbor and back here. ' .. cost ..' gold for non-premium members, premium members sails for free.', cid)
        npcHandler:addFocus(cid)

    elseif(not npcHandler:isFocused(cid)) then
        return false

    elseif msgcontains(msg, "bye") or msgcontains(msg, "farewell") then
        npcHandler:say("Goodbye, take care!", cid, TRUE)
        npcHandler:releaseFocus(cid)

    elseif msgcontains(msg, "sail") or msgcontains(msg, "travel") then
        npcHandler:say("Would you like to sail to {Lake Arbor}?", cid)
        sail = 1
       
    elseif(msgcontains(msg, 'yes') and sail == 1) then
        if isPremium(cid) then
            cost = 0
        end
        if(doPlayerRemoveMoney(cid, cost) == TRUE) then
            player:teleportTo(newPosition, true)
            if not player:isInGhostMode() then
                oldPosition:sendMagicEffect(CONST_ME_POFF)
                newPosition:sendMagicEffect(CONST_ME_TELEPORT)
            end
            selfSay('You\'ve successfully arrived to Lake Arbor.', cid)
        else
            selfSay('Sorry, you don\'t have enough gold coins to sail with me.', cid)
        end   
    end

    return true

end

npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:setMessage(MESSAGE_WALKAWAY, "Well, you could at lest say goodbye!")

Thanks in advice,
