Why does this script not work? It is supposed to destroy the ScreenGui for good.

After destroying the script's parent from the StarterGUI, you can reset and the same GUI it is supposed to destroy will pop back up on the screen. It should only appear once and never show again, correct?

wait(1) 

local RHCcontrol = script.Parent.Parent.RHCcontrol

script.Parent.Background.Button.Accept.MouseButton1Click:connect(function()
    if RHCcontrol.Frame.Visible == false then
    RHCcontrol.Frame.Visible = true

        wait(.1)

        script.Parent:Destroy()
    end

end)
