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()
