What am I doing wrong Im trying to define a humanoid and its not working?

You want to let it print the Name of the humanoid if you want to use print()

hum = script.Parent.Parent.Humanoid
print(hum.Name)

But, a Humanoid inside of a players character would not be any parent of ServerScriptService. The serverscriptservice is only parented by "game".

If you want the player's humanoid, do this:

game.Players.PlayerAdded:connect(function(player)
	player.CharacterAdded:connect(function()
		local hum = player.Character:WaitForChild("Humanoid")
		print(hum.Name)
	end)
end)
