OTClient Auto Wild growth

[Rolandos]

Hi, anyone can helb me to fix this script for OTCV8 Client?

local spot = nil
local id = Item.GetID("wild growth rune")

function onSpeak(c, msg)
    msg = msg:lower()
    c:SendYellowMessage(Self.Name(), msg)
    if msg == "spot" then
        spot = Self.Position()
        c:SendOrangeMessage("Xenobot", "Coordinates updated: ("..spot.x..", "..spot.y..", "..spot.z..")")
    elseif msg == "reset" then
        spot = nil
        c:SendOrangeMessage("Xenobot", "Coordinates reset.")
    end
end

function onClose(c)
end

local c = Channel.Open("Wild Growth", onSpeak, onClose)
c:SendOrangeMessage("Xenobot", "Welcome to Tools Channel! Type 'spot' while standing on the coordinates you want to place a magic wall. Type 'reset' to clear all values.")

Module.New("Module:RuneField", function(mod)
    if (spot ~= nil) then
        if (Map.IsTileWalkable(spot.x, spot.y, spot.z)) then
            Self.UseItemWithGround(id, spot.x, spot.y, spot.z)
        end
    end
    mod:Delay(200)
end)
