I made a script so that if I touch a circle it enables a GUI but it doesnt enable again?

So I was making a trader to sell Swords and I made a gui for it which the gui has a script where if you touch a circle in the map it makes the gui visible which works then later I made a button so it would close the gui but when you press it it works but later when you try to open the gui again using the button it doesnt work here are the codes I dont know how to fix this could anybody show me what is wrong or tell me how to fix it.

--- This is the Button For it to close.
function click()
    if script.Parent.Parent.Visible == true then
    script.Parent.Parent.Visible = false
    else script.Parent.Parent.Visible = true
    end
end

script.Parent.MouseButton1Click:connect(click)

---- Touch Script For the Circle Object
function touch(hit)
    if game.Players:findFirstChild(hit.Parent.Name) ~= nil then
        local player = game.Players[hit.Parent.Name]
        if player.PlayerGui:findFirstChild("Info") == nil then
            local gui = script.Info:clone()
            gui.Parent = player.PlayerGui
            repeat
                wait()
            until (player.Character.Torso.Position - script.Parent.Position).magnitude > 5
            gui:remove()
        end
    end
end

script.Parent.Touched:connect(touch)
