Why is this open/close gui not working? [TWEEN]

So, I am trying to make a gui open/close with tweening, can someone explain why this is not working? It will open, but it will not close afterwards.

script.Parent.MouseButton1Click:Connect(function()
	local work = false
	if work == false then
		work = true
		script.Parent.Parent:TweenPosition(UDim2.new(0.736, 0,0.304, 0))
		wait(1)
	else
		work = false
		script.Parent.Parent:TweenPosition(UDim2.new(0.932, 0, 0.304, 0))
		wait(1)
	end
end)

This is a local script. Any help will be greatly appreciated.

Make work a script-wide variable.

The issue here is that your variable, work, is being created from inside the function - and thus is never actually true and not up-to-date with the current state of your UI.
