Why isn't my script setting a value to false?

I'm making a help gui for new players, and I want a system where if you click the button that shows the help screen again after clicking it once already, it will stop showing it. This system isn't working and I don't know why. It does tween it back to it's original position when you click it again. But then if you try to click it a third time, nothing happens. Here's my code

local AlreadyClicked = false

script.Parent.MouseButton1Down:Connect(function()
	
	local HelpGUI = script.Parent.Parent.HelpGUI
	
	if AlreadyClicked == true then
		AlreadyClicked = false
		HelpGUI:TweenPosition(UDim2.new(-0.179, 0,0.306, 0),"Out","Quad",1,false)
	end
   
	
	
	
	HelpGUI:TweenPosition(
	                      UDim2.new(0.101, 0,0.309, 0),
		                  "Out",
		                  "Quad",
		                  1,
		                  false)
	                      
	AlreadyClicked = true
end)
