My open/close gui not working as i expected? it wont close again what did i do wrong?

Ok, buddy, many issues with this. First of all, please indent. The indentation on this is not good. Next, this is way more complicated then it has to be. Next, use 'Activated' instead of MouseButton1Click, so if a phone clicks the button, it still works.

script.Parent.Activated:Connect(function()
	if script.Parent.Parent.Value.Value == true then
		script.Parent.Parent.Size = UDim2.new(1, 0, 0, 50)
		script.Parent.Parent.Play.Visible = false
		script.Parent.Parent.c.Visible = false
		script.Parent.Parent.d.Visible = false
		script.Parent.Text = "Rainbow Road"
		wait("insert wait time here")
		script.Parent.Parent.Value.Value = false
	else
		script.Parent.Parent.Size = UDim2.new(1, 0, 0, 200)
		script.Parent.Parent.Play.Visible = true
		script.Parent.Parent.c.Visible = true
		script.Parent.Parent.d.Visible = true
		script.Parent.Text = "Rainbow Road"
		wait("insert wait time here")
		script.Parent.Parent.Value.Value = true
	end
end)

The simple fix is the else command.
