it's self-explanatory, but I have no idea what the problem is, in case you don't want to see the link here's the code

script.Parent.MouseButton1Click:Connect(function()
	wait(0.01)
	script.Parent.Parent.Parent.Active = false
	script.Parent.Parent.Parent.Visible = false
	script.Parent.Parent.Active = false
	script.Parent.Parent.Visible = false
	script.Parent.Parent.Parent.Parent.CI.Active = false
	script.Parent.Parent.Parent.Parent.CI.Visible = false
	script.Parent.Parent.Parent.Parent.Begin.Active = false
	script.Parent.Parent.Parent.Parent.Begin.Visible = false
	script.Parent.Parent.Parent.Parent.Parent.CMDActivate.Active = true
	script.Parent.Parent.Parent.Parent.Parent.CMDActivate.Visible = true
	script.Parent.Parent.Parent.Parent.Parent.CMDActivate.CmdActivationScript.Disabled = true
	script.Parent.Parent.Parent.Parent.Parent.OriginalPositionOpeningScript.Disabled = false
end)
