Do you have many page connectors on schematic? You can use the following tips to make sure that page connectors were connected properly.
Page connector name becomes encapsulated in rectangle if the page connector has been connected to another page connector by name. Also page connector gets green dot (small green circle) if it was connected to bus.
Thanks, Alex! That answers another question I had: why do some have boxes and a few only have an underline? Now I know.
(Yes, the schematic I'm working on is 14 pages, with nets combined into logical buses to go from page to page.)
However, it's still nice to be able to list all the instances, since I have the same bus used on several pages. I guess if I see any one page where there is not a box around the name, it's a clear indication that I got the name wrong, though it's still possible I could have gotten it wrong on just two of the pages. It might be things like putting an underscore in a name most places but accidentally leaving it out of some. I can always check the connections of the nets in the bus, of course, and also the list of nets included in the bus.
