Thanks Morten,
So basically it's saying, if it matches that number and the user does not
have the permission to call it then block. I am a bit unclear of the AVP
stuff to be honest, is this trying to match the username to the attribute
in the table? And what value does it look for in the table?
Thanks,
Keith
