Access 2000 Update query

I am teaching Beginner’s MS Access and, to my surprise, could not get an update query to work right on the PC’s in the lab that I am using, although it works fine on my PC at home. The updated fields appear in the query and the update is performed but not all of the fields appear. For instance, I am adding 10% to cost of Tour but I also want the Tour name and other fields that I have chosed to place in the design grid to appear next to the corresponding updated figure. The only columns that appear on the lab PC’s are those that have calculations. Does anyone know what is happening?
