Why does my gui only tween once and then stops working?

I'm trying to make a gui that changes positions using the Tweenposition function but it only works once and won't work again until my player respawns.

Local script located in textbutton:

local inuse = false

script.Parent.MouseButton1Click:connect(function()
	if inuse == false then
		inuse = true
		script.Parent.Parent:TweenPosition(UDim2.new(0, 350,0, 230))
		wait(1.5)
	end

end)

script.Parent.MouseButton1Click:connect(function()
	if inuse == true then
		inuse = false
		script.Parent.Parent:TweenPosition(UDim2.new(0, 10,0, 230))
		wait(1.5)
	end

end)

Thanks!
