For some reason, my ScreenGUI is only opening once. It's from a ClickDetector. This is a server script. Also don't tell me to use "Visible" because that's not a property in ScreenGUIs.
local clickdetector = game.Workspace.SELECT.ClickDetector clickdetector.MouseClick:Connect(function(player) player:WaitForChild('PlayerGui').SpawnCar.Enabled = true end)
