Can someone teach me how to make it where I can click the button unlimited?

So I am making a shop gui but I dont know how I make it where you can click the shop button to open and it click the x to close it? I dont need help with the x or how to click it to make it visible but I want someone to teach me how I make it where I can click the shop and exit it unlimited? Because it only works once?

This video should help :) https://www.youtube.com/watch?v=aSwGwX7HbOE

U can use this:

local deb = false
:Connect(function()
	if deb = false then
		deb  = true

		if Gui.Enable == true then
			Gui.Enable = false else
		Gui.Enable = true

		wait(1)
		deb = false
	end
end)
