How do I add a model with a clickdetector and a script in it?

Ok, Im doing a house that has a forsalesign and when you click on it you own the house. I need help with the forsalesign removal and for it to come back when the player who claimed the house leaves the game. I have tried this so far but it didn't work

local clickDetector2 = script.Parent:WaitForChild("ForSaleSign1ClickDetector")
local Forsalesign = script.Parent
local Player = game.Players.LocalPlayer
    clickDetector2.MouseClick:Connect(function(player)
        if player.name ~= game.Workspace.houses.House2.CurrentOwner.Value then
            game.Workspace.houses.House1.CurrentOwner.Value = player.Name
            script.Parent.Parent["Nobody's House"].Name = game.Workspace.houses.House1.CurrentOwner.Value
            wait(0.1)
            script.Disabled = true
            Forsalesign.Wood.Transparency = 1
            Forsalesign.Wood.CanCollide = false
            Forsalesign.RedPart.Transparency = 1
            Forsalesign.RedPart.Decal.Transparency = 1

            Player.PlayerRemoving:Connect(function(player)
                Forsalesign.Wood.Transparency = 0
                Forsalesign.Wood.CanCollide = true
                Forsalesign.RedPart.Transparency = 0
                Forsalesign.RedPart.Decal.Transparency = 0

            end)

            end
        end)
