Why does this function not play out like it's supposed to?

I explain the problem in the script.

local Storage = game.ServerStorage
game.Workspace.Timer.Countdown.Value = 300

function markDoom () --This is the function that does not work, scroll to the bottom for more information.
	local Mark = Storage.SuddenDeathMarker:Clone()
	Mark.Parent = game.Workspace
	local doomScroll = Instance.new("Message")
	doomScroll.Text = "Hurry! All players must enter the red box in the center of the map or they will be DESTROYED!!"
	wait(7)
	doomScroll:Destroy()
end

function suddenDeath ()
	game.Workspace.SuddenDeathMarker:Destroy()
	local x = Instance.new("Message")
	x.Text = "Sudden Death--2 Minutes Remaining"
	game.Lighting.ChangeColor.TintColor = Color3.new(255, 0, 0)
	wait(5)
	x.Parent = game.Workspace
	wait(5)
	x:Destroy()
	Storage.SuddenDeathWall.Parent = game.Workspace
	game.Workspace.Zone:Destroy()
end

function movezone ()
	local ZoneClone = Storage.Zone:Clone()
	ZoneClone.Parent = game.Workspace
	ZoneClone.Posision = CFrame.new(-12.355, -128.196, 209.416)
end

function spawnplayers ()
	Storage.GameSpawn.Parent = game.Workspace.Spawns
	wait(1)
	
	for i, player in ipairs(game.Players:GetPlayers()) do
		player.RespawnLocation = game.Workspace.Spawns.GameSpawn
		if player.Character then
			local hum = player.Character:FindFirstChild('Humanoid')
			if hum then
				hum.Health = 0
			end	
		end
	end
	
	local information = Instance.new("Message")
	information.Text = "Run For Your Life, The Hounds Have Benn RELEASED!!!"
	information.Parent = game.Workspace
	wait(5)
	information:Destroy()
	
	wait(3)
	
	game.Workspace.Timer.Countdown.Value = 300
	
	game.Workspace.Spawns.GameSpawn.Parent = Storage
	movezone()

end

function resetplayers ()
	for i, player in ipairs(game.Players:GetPlayers()) do
		if player.Character then
			local hum = player.Character:FindFirstChild('Humanoid')
			if hum then
				hum.Health = 0
			end	
		end
	end
	
	game.Lighting.ChangeColor.TintColor = Color3.new(255, 255, 255)
	
end
	
game.Workspace.Test.Touched:Wait()
spawnplayers()
wait(143)
markDoom()--This is the function that does not work and it is the same thing with everything after it. Can someone help me fix this.
wait(30)
suddenDeath()
wait(120)
resetplayers()
