How can I make it Highlight the Shelf that not Stocked?

[xl_Beam]

1. What do you want to achieve? Keep it simple and clear!
   I wanted to make a restock systems that when players interacted and It will highlight shelf that currently not stocked.

2. What is the issue? Include screenshots / videos if possible!
   It not adding a highlight to the shelf.

3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
   I have tries Searching in Devforum and Googles but couldn’t find possible way.

local Players = game:GetService("Players")
local ServerStorage = game:GetService("ServerStorage")
local Workspace = game:GetService("Workspace")
local ReplicatedStorage = game:GetService("ReplicatedStorage")

local Assets = ServerStorage.Assets
local anim = Assets.Animations.Pickup
local Set = ReplicatedStorage.Request.Set
local Create = ReplicatedStorage.Request.Create

local Restock = Workspace.Worlds.Objectives.Restock
local Asset = Restock.Assets:GetDescendants()
local Shelf = Restock.Shelf:GetDescendants()

local playerTracks = {}

local function Highlight(player, Shelf)
	if Shelf and Shelf.Stocked and Shelf.Stocked.Value ~= nil then
		if Shelf.Stocked.Value == false then
			Create:FireClient(player, Shelf)
		elseif Shelf.Stocked.Value == true then
			print("a")
		end
	end
end

local function Interaction(player, box)
	local Character = player.Character
	if not Character then
		return
	end

	local humanoid = Character:WaitForChild("Humanoid")

	if (not Workspace.Worlds.Temp:FindFirstChild(player.Name .. "_Boxes")) and (not Character:FindFirstChildOfClass("Tool")) and (not Workspace.Worlds.Temp:FindFirstChild(player.Name .. "_Garbage")) then
		humanoid.WalkSpeed = 9
		Character.IsCarrying.Value = true
		
		local model = Assets.Boxes:FindFirstChild("Box"):Clone()
		model.Parent = Workspace.Worlds.Temp
		model.CanCollide = false
		model.Name = player.Name .. "_Boxes"

		local weldConstraint = model:FindFirstChildWhichIsA("WeldConstraint")
		if not weldConstraint then
			weldConstraint = Instance.new("WeldConstraint")
			weldConstraint.Parent = model
			model.CFrame = Character.HumanoidRootPart.CFrame * CFrame.new(0, -0.3, -2)
			weldConstraint.Part0 = model
			weldConstraint.Part1 = Character.UpperTorso
		else
			weldConstraint:Destroy()
		end
				
		local track = humanoid:LoadAnimation(anim)
		track.Priority = Enum.AnimationPriority.Movement
		track.Looped = true
		track:Play()
		Set:FireClient(player,box.ProximityPrompt,false)

		model.Equipped:Play()
		playerTracks[player] = track
	end
end

local function Drop(player, box)
	local Character = player.Character
	if not Character then
		return
	end

	local humanoid = Character:WaitForChild("Humanoid")

	local existing = Workspace.Worlds.Temp:FindFirstChild(player.Name .. "_Boxes")
	if existing then
		existing.Unequipped:Play()
		task.wait(.3)
		box.Parent.Shelf.Stocked.Value = true
		existing:Destroy()
		Character.IsCarrying.Value = false
		humanoid.WalkSpeed = 16
		Set:FireClient(player,box.ProximityPrompt,false)

		for i,v in pairs(box.Parent.Shelf.Boxes:GetChildren()) do
			v.Transparency = 0
			v.CanCollide = true
		end

		local track = playerTracks[player]
		if track then
			track:Stop()
			playerTracks[player] = nil
		end
	end

end

for _, prompt in pairs(Asset) do
	if prompt:IsA("ProximityPrompt") then
		prompt.Triggered:Connect(function(player)
			Interaction(player, prompt.Parent)
			for _, prompt1 in pairs(Shelf) do
				if prompt1:IsA("ProximityPrompt") then
					Set:FireClient(player,prompt1,true)
					Highlight(prompt1.Parent)
				end
			end
		end)
	end
end

for _, prompt in pairs(Shelf) do
	if prompt:IsA("ProximityPrompt") then
		prompt.Triggered:Connect(function(player)
			local pShelf = prompt.Parent.Parent.Shelf

			local cTrashBin = pShelf:FindFirstChild("Trash Bin")

			if cTrashBin then
				if cTrashBin:IsA("Model") and cTrashBin.Parent:FindFirstChild("Stocked") then
					if cTrashBin.Parent.Stocked.Value == true then
						cTrashBin.Parent.Stocked.Value = false
						Set:FireClient(player, prompt.Parent, false)
					end
				end
			end

			Drop(player, prompt.Parent)
			for _, prompt1 in pairs(Asset) do
				if prompt1:IsA("ProximityPrompt") then
					Set:FireClient(player, prompt1, true)
				end
			end
		end)
	end
end

and this is client:

local player = game.Players.LocalPlayer
local character = player.Character
local IsCarrying = character:WaitForChild("IsCarrying")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Create = ReplicatedStorage.Request.Create
local Set = ReplicatedStorage.Request.Set

if IsCarrying and IsCarrying:IsA("BoolValue") then
	local function check()
		if IsCarrying.Value == true then
			game:GetService("StarterGui"):SetCoreGuiEnabled(Enum.CoreGuiType.Backpack, false)
		else
			game:GetService("StarterGui"):SetCoreGuiEnabled(Enum.CoreGuiType.Backpack, true)
		end
	end

	IsCarrying:GetPropertyChangedSignal("Value"):Connect(function()
		check()
	end)
end

Set.OnClientEvent:Connect(function(Prompt,Value)
	Prompt.Enabled = Value
end)

Create.OnClientEvent:Connect(function(Shelf)
	local a = script.Highlight:Clone()
	a.Parent = Shelf
end)

Honestly, the simplest way to do it is jus to create a part, make it yellow and tone the transparency down so it’s not a yellow brick.

I’m using a highlight so it highlight the entire shelf

[Midnightific]

Yep, so you can create a part (Instance.new) and then size it appropriately to fit the shelf!

if the highlight doesn’t show up then it’s a bug that still isn’t fixed.

Thank for Helping, But I think I found the Solution.
