What was the service that was requested and the locations used? You can check the values in the shipping quote server behavior to see what they are set to. Some services are only available from certain locations. For example, you would not be able to use a global delivery option if both the shipper and destination are in the same country. You can post back with the confirm page also to let us see how it is setup. If you post back with this make sure to remove any sensitive details first.
