Randomization between several death sounds?

Somebody was trying to help me randomize custom death sounds and gave me this script.

IDs = {130965811, 131045862, 131045876}

game.Players.PlayerAdded:connect(function(player)
repeat wait() until player.Character
player.CharacterAdded:connect(function(character)
character:WaitForChild("Humanoid").Died:connect(function(human)
sound = "http://www.roblox.com/asset/?id="..tostring(IDs[math.random(#IDs)])
sound:Play()
end)
end)
end)

However, it doesn't work. Is there a way to salvage this?
