Creating a character for teams only lasting for once, help?

I know how to make characters for teams, but i have problems when the character dies. When the character dies they go back to their original avatar. I have no idea what to do, i tried doing 'While true do' which well... Roblox studio just dies. I would like if someone could help me Thanks.

There is an event called Humanoid.Died inside the character

game.PlayersAdded:Connect(function(player)
	local character = player.Character
	character.Humanoid.Died:Connect(function()
		player.CharacterAppearanceId = "rbxassetid://"  -- Or it is "roblox.com/asset/?id="  Idk
	end)
end)

I hope this helps!
