Anyone know how to fix this team change camera manipulation?

I recently tried making some team change camera manipulation, where when you first join you will be looking over two ships, one being the "dark side" ship and the other the opposite. Then when you click the team button, a gui below comes up with select (like in jailbreak) and you will then be looking inside the teams ship that you pressed. Im getting one error:

Line 7- Teamchange is not a valid member of PlayerGUI Here is the script:

--// Client
    local Player = game.Players.LocalPlayer
    local Character = Player.Character or Player.CharacterAdded:Wait()
    local Camera = workspace.CurrentCamera

    --// GUIs
    local PlayButton = script.Parent.Parent.Teamchange.Frame.Light --Script.parent.parent is starter Gui
    local play = script.Parent.Parent.Teamchange.Frame.Dark
    local confirm = script.Parent.Parent.Teamchange.Frame.Light.TextButton
    local confirm2 = script.Parent.Parent.Teamchange.Frame.Dark.TextButton

    --// Main
    repeat wait()
        Camera.CameraType = Enum.CameraType.Scriptable
    until Camera.CameraType == Enum.CameraType.Scriptable   
        Camera.CFrame = workspace.CameraPart.CFrame

    PlayButton.MouseButton1Click:Connect(function()
        Camera.CFrame = workspace.CameraPart3.CFrame
    end)
    play.MouseButton1Click:Connect(function()
        Camera.CFrame = workspace.CameraPart2.CFrame
    end)

    confirm.MouseButton1Click:Connect(function()
        Camera.CameraType = "Custom"
    end)

    confirm2.MouseButton1Click:Connect(function()
        Camera.CameraType = "Custom"
    end)

Any ideas why its not working? Help would be very appreciated ;)
