What do I need to do in order to make the animation work?

I following doing AlvinBlox's tutorial on how to animate but I haven't been able to make it work. I did the following:

• Inserted ScreenGUI into StarterGUI

• Inserted TextButton into ScreenGUI

• Inserted LocalScript and put in the following

  script.Parent.MouseButton1Click:Connect(function()

game.ReplicatedStorage.RemoteEvent:FireServer("2979587799")

end)

• Inserted RemoteEvent in ReplicatedStorage

• Inserted Script into Workspace and put the following

  game.ReplicatedStorage.RemoteEvent.OnServerEvent:Connect(function(player,animationID)

local animation = Instance.new("Animation")

animation.AnimationId = "http://www.roblox.com/Asset?ID="..animationID

local loadedAnimation = game.Workspace(player.Name).Humanoid:LoadedAnimation(animation)

loadedAnimation:Play()

end)

I have tested it and played in-game with no luck. Are there any errors? Is the method simply outdated? What should I do instead?
