network.initialize server please

i have no idea whats wrong with this but the console says:
No appropriate version of ‘UnityEngine.Network.InitializeServer’ for the argument list ‘(int, String, boolean)’ was found.

Network.InitializeServer(32, port, false);

the port is a GUI.textField
HELP!

Try converting it to an int as such :

int portInt = System.Convert.toInt32(port);

Network.InitializeServer(32, port, false);

Network.InitializeServer
