fake error

i am getting compiler error witch i think are fake, here is the script

function Start() {
	MasterServer.ipAddress = "127.0.0.1";
	MasterServer.port = 23466;
}

i am getting:
‘ipAddress’ is not a member of ‘MasterServer’
‘port’ is not a member of ‘MasterServer’

is MasterServer a script name?

if so do

    MasterServer().ipAddress = "127.0.0.1";
    MasterServer().port = 23466;
