How do I make the 3,2,1 ImageLabel work in this script?

I added the 3,2,1 Decal in the ImageLabel. This is PlaceRebuilder's but I want to test them out. Well, it didn't work for some reason. This is the script (LONG SCRIPT):

local checkpoint1 = game.Workspace.MapHolder.Map1Beginner.Checkpoint1
local checkpoint2 = game.Workspace.MapHolder.Map1Beginner.Checkpoint2
local checkpoint3 = game.Workspace.MapHolder.Map1Beginner.Checkpoint3

local redLight = game.Workspace.MapHolder.Map1Beginner.StartLight.RedModel.LightBulb.PointLight
local yellowLight = game.Workspace.MapHolder.Map1Beginner.StartLight.YellowModel.LightBulb.PointLight
local greenLight = game.Workspace.MapHolder.Map1Beginner.StartLight.GreenModel.LightBulb.PointLight
local startBarrier = game.Workspace.MapHolder.Map1Beginner.StartBarrier
local image = game.StarterGui.ScreenGui.ImageLabel
image.Visible = false

local raceInProgress = false

local lobbySpawn = game.Workspace.LobbySpawn
local trackSpawn = game.Workspace.MapHolder.Map1Beginner.TrackSpawn

local minimumPlayers = 1

function destroyCars()
	for _, object in pairs(game.Workspace:GetChildren()) do
		print(object.Name)
		if object.Name == "Car" then
			print("This is a car! We need to destroy it!")
			object:Destroy()
		end
	end
end

function createCars()
	for _, object in pairs(game.ServerStorage:GetChildren()) do
		local carCopy = object:Clone()
		carCopy.Parent = game.Workspace
		carCopy:MakeJoints()
	end	
end


function showVictoryMessage(playerName)
	local message = Instance.new("Message")
	message.Text = playerName .. " has won!"
	message.Parent = game.Workspace
	wait(2)
	message:Destroy()
end


function checkpoint1hit(otherPart)
	print("Checkpoint 1 was hit")
	print(otherPart.Name)
	if otherPart ~= nil and otherPart.Parent ~= nil and otherPart.Parent:FindFirstChild("Humanoid") then
		print("A player hit me!")
		if not checkpoint1:FindFirstChild(otherPart.Parent.Name) then
			local playerTag = Instance.new("StringValue")
			playerTag.Parent = checkpoint1
			playerTag.Name = otherPart.Parent.Name
		end
		
		if checkpoint3:FindFirstChild(otherPart.Parent.Name) and raceInProgress then
			print("Player wins!")
			raceInProgress = false
			showVictoryMessage(otherPart.Parent.Name)
		end
	end
end

function checkpoint2hit(otherPart)
	print("Checkpoint 2 was hit")
	print(otherPart.Name)
	if otherPart ~= nil and otherPart.Parent ~= nil and otherPart.Parent:FindFirstChild("Humanoid") then

			local playerTag = Instance.new("StringValue")
			playerTag.Parent = checkpoint2
			playerTag.Name = otherPart.Parent.Name
		end
	end
end

function checkpoint3hit(otherPart)
	print("Checkpoint 3 was hit")
	print(otherPart.Name)
	if otherPart ~= nil and otherPart.Parent ~= nil and otherPart.Parent:FindFirstChild("Humanoid") then
		print("A player hit me!")
		if not checkpoint3:FindFirstChild(otherPart.Parent.Name) and checkpoint2:FindFirstChild(otherPart.Parent.Name) then
			local playerTag = Instance.new("StringValue")
			playerTag.Parent = checkpoint3
			playerTag.Name = otherPart.Parent.Name
		end
	end
end

The Images are in Line 096 to 118. Sorry if it is long, but please, if you can, fix it. :)

The Imagelabel ID's are all the same.
