Thank you CAM. Unfortunately, even with all the above in place, the class lists are still not linking to course membership for some subjects. For example, I have an A2 student in classes for three subjects, her timetable is fine etc. but when I check which courses she is in, only 1 shows.
Is there anywhere else I need to link class lists to course lists?
As I said, up till this year we uploaded timetable from Timetabler, so I am thinking maybe there is something in Nova-T that we forgot to do. I used to blame all my troubles on a third party product, but do not have that excuse now ;-)
