Roblox Studio：if then else 错误，尝试了一切

local clicker = script.Parent.ClickDetector
local canclick = true

local chance = math.random(1,3)
if chance == 1 then
    clicker.MouseClick:connect(function(Player)
        if canclick then
            if Player:FindFirstChild("Stand").Value == "The World" then
                Player:FindFirstChild("Stand").Value = "Nightmare World"
                canclick = true
                Player:LoadCharacter()
                script.Parent:Remove()
            else
                clicker.MouseClick:connect(function(Player)
                    if canclick then
                        Player:FindFirstChild("Stand").Value = "None"
