Why the pop up billboard Gui not showing when approaching?

My code is like this, it should work! When the distance between Local Player and the noticePad, the GUI will show.

--Codes above is ignored.
while wait() do
	for i,Notice in pairs(BillBoards) do
		local NoticePad = Notice.PrimaryPart
		local dist = (plr.Character.HumanoidRootPart.Position - NoticePad.Position).magnitude
		if dist <= 30 then --It works! But it is not visible >:(
			script.Parent.Parent.Adornee = NoticePad
			script.Parent.Parent.Enabled = true
			script.Parent.Visible = true
			script.Parent.Nearby:Fire(NoticePad)
		else
			script.Parent.Parent.Enabled = false
		end
	end
end

Please help me, sincerely.
