Isn't this a summary field when sorted by Title? Since this is a summary of a calculated field (# of quarters) I think you would need to make it a stored field.
Just an aside, not sure what your % column is calculating.
Couple of things.
In Quarter, I see Fall, Winter, Spring, F/W/S, F/W/S (A.I.). What is A.I.?
Not knowing about that, I suggest that you create an auto-entered number field called something like, "NumberOfQuarters". Make it an auto-enter field, and use the formula ValueCount ( Quarter ). REMOVE the options which allow for F/W/S. If I click just Fall, NumberOfQuarters would be 1. Click Fall, Winter, and Spring, it would be 3. ValueCount would be very helpful for you, I think.
If you did that, then had a report in which you sorted by the "Appointment To" field, you'd be very nearly there. Just add a field called NumberOfQuarters_smry, of type summary. It would be the Total of NumberOfQuarters. On the report layout, you could add a subsummary part when sorted by Appointment To. Put the NumberOfQuarters_smry field into that part.
Go to the layout, sort, and all of the totals you're after would be calculated automatically. Give that a shot.
That helped a lot, dtcgnet.
The reason there was both a F/W/S option and a F/W/S (A.I.) option isn't very interesting -- it's based on the fact that the pay period and start date for fall+winter+spring appointments is different for Associate Instructors than it is for other people. Not worth going into detail about. I can change the pay and start date calculations elsewhere and make everything work out in the end.
Glad it helped. Had another thought.
In your subsummary report, create a total of two subsummary parts. One for when the found set is sorted by Appointment To and one when it's sorted by Employee and Appointment To. Add that summary field to each part.
When you sort by Appointment To (only), you'll see something like:
Those will be totals for each category of Appointment To.
When you sort by Employee and Appointment To, you'll see:
John Doe 7
Bill Smith 9 (the total for Bill Smith)
Hope that helps.
