How do I make a BillboardGui/Part visible to a certain team?

The localscript that fires it

local FakeOrder = game.ReplicatedStorage.Commands.FakeCommand
local Order = game.ReplicatedStorage.Commands.EnemySpot
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local remoteEvent = ReplicatedStorage:WaitForChild("Command")
local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()
local UIS = game:GetService("UserInputService")
local Opened = script.Parent.Parent.Parent.OpenedVal
local Team = script.Parent.Parent.Parent.Parent.Parent.TeamColor

UIS.InputBegan:connect(function(keyCode)
	if keyCode.keyCode == Enum.KeyCode.Y then
		if Opened.Value == true then
			script.Parent.Parent.Parent.Enabled = false
			local CloneFakeOrder = FakeOrder:Clone()
			CloneFakeOrder.CFrame = CFrame.new(Vector3.new(Mouse.Hit.X, Mouse.Hit.Y, Mouse.Hit.Z))
			local position = CloneFakeOrder.Position
			remoteEvent:FireServer(Order, position, Team)
			script.Parent.Parent.Parent.Sound:Play()
			wait(0.1)
			Opened.Value = false
			print("done")
		end
	end
end)

script in serverscript

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local remoteEvent = ReplicatedStorage:WaitForChild("Command")
local remoteEvent2 = ReplicatedStorage:WaitForChild("DeleteCommand")


remoteEvent.OnServerEvent:Connect(function(player, Order, position, Team)
	local ClonedCommand = Order:clone()
	local Command = ClonedCommand.Name
	ClonedCommand.Parent = workspace
	ClonedCommand.Position = position
	local Theam = Team.Name
	local ClohnedCommand = ClonedCommand
	remoteEvent2:FireAllClients(Theam ,ClohnedCommand)
	print("2done")
end)

Another localscript in StarterGui

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local remoteEvent = ReplicatedStorage:WaitForChild("DeleteCommand")

remoteEvent.OnClientEvent:Connect(function(player, Theam ,ClohnedCommand)
	if script.Parent.Parent.TeamColor == Theam then
		print("3done")
	else
		ClohnedCommand.BillboardGui:destroy()
		print("3done")
	end
end)

The error I'm getting is: Players.Player1.PlayerGui.LocalScript:8: attempt to index nil with 'BillboardGui'

Any help would be appreciated
