I have the same problem as Nolan. I have a top sheet with two sub sheets that are linked with a bus. However, I end up with an error about duplicate net names and it will reference one net in each sheet.
If I remove one of the sheets and put its circuit in the TopSheet, everything works fine. I can't find a tutorial that covers two sheets on the same hierarchical level that are connected with a bus. It is usually connecting sheets vertically.
Thanks for any help!
