Multiplayer Tutorial android problem

Hi, im following the multiplayer tutorial for mobile and coming across problems when trying to build for my android device. When testing in Unity i have no problems, but when transferring over to mobile i encounter a lot of problems!.

Which are..

Assets/ConnectionGUI.js(40,1): BCE0005: Unknown identifier: 'ipaddress'.

Assets/ConnectionGUI.js(41,1): BCE0005: Unknown identifier: 'port'.

Assets/ConnectionGUI.js(42,49): BCE0005: Unknown identifier: 'ipaddress'.

Assets/ConnectionGUI.js(42,63): BCE0005: Unknown identifier: 'port'.

Error building Player because scripts had compiler errors UnityEditor.BuildPlayerWindow:BuildPlayerAndRun()

Exception: Error building Player because scripts had compiler errors UnityEditor.BuildPlayerWindow.BuildPlayerWithDefaultSettings (Boolean askForBuildLocation, BuildOptions forceOptions) UnityEditor.BuildPlayerWindow.BuildPlayerAndRun ()

Assets/ConnectionGUI.js(22,9): BCW0012: WARNING: 'UnityEngine.Network.useNat' is obsolete. No longer needed. This is now explicitly set in the InitializeServer function call. It is implicitly set when calling Connect depending on if an IP/port combination is used (useNat=false) or a GUID is used(useNat=true).

Assets/ConnectionGUI.js(24,9): BCW0012: WARNING: 'UnityEngine.Network.InitializeServer(int, int)' is obsolete. Use the IntializeServer(connections, listenPort, useNat) function instead

I am going to attempt solving the problem now, but was wondering if there has been improvements on the newer unities that could restrict the old methods in the tutorial, thanks!
