Humanoid.Died not activating

Hook up the function to a character added callback.

Do you mean something like this?

	local Character = Player.Character or Player.CharacterAdded:Wait()
	Player.CharacterAdded:Connect(function(Char)
		Character = Char
		print('new char')
		Character.Humanoid.Died:Connect(function()
			print('char')
			if not Player:FindFirstChild('DogeTag') then
				print('not doge')
				if table.find(PlayingPlayers,Player) then
					print('is playing')
					Values.KillFeed.Value = Player.Name..' was killed by the Doge!'
					local ReturnValue = table.find(PlayingPlayers,Player)
					table.remove(PlayingPlayers,ReturnValue)
				end
			end
		end)
	end)
