How do I make something that is printed, enable a Screen GUI?

I already made it that if you click on something, it will print "Clicked!", but I want to make it so that if "Clicked!" is printed, i want it to enable a Screen Gui, how do i do that?

(I am assuming you meant ClickDetector)

script.Parent.ClickDetector.MouseButton1Click:Connect(function(player)
	if player.PlayerGui.ScreenGui.Frame.Visible == true then --//change to your screen gui
		player.PlayerGui.ScreenGui.Frame.Visible = false
	elseif player.PlayerGui.ScreenGui.Frame.Visible == false then
		player.PlayerGui.ScreenGui.Frame.Visible = true
	end
end
