How do i make a Gui pop up on a click detector?

Im trying to make a GUI That opens on a click detector, I have the opening and closing sequence done but after i close the GUI It wont open again, Does anyone know how to fix this?

Opening Script:

local function click(player)
	player.PlayerGui.ScreenGui.Frame.Visible = true
end

script.Parent.ClickDetector.MouseClick:Connect(click)

Closing script: (inside a TextButton)

script.Parent.MouseButton1Click:Connect(function()
	script.Parent.Parent.Visible = false
end)
