Did you use Data|Subtotal to add the =subtotals()?
If yes, then I'd remove those subtotals, add the new person, sort the data and
If you do this lots of times, you may want to record a macro when you do it.
I have a single page spreadsheet (needed for SubTotal() to work), separated
into 65 sheets via Page Break Preview. The top cell of each page in Col A
contains the student's name (last name, first name). If I add a student,
how can I then sort the pages by the student's last name?
Acceptable alternative: Have each student on their own page with sheets
named Lastname Firstname, sort those, and still be able to Subtotal in
cells on those sheets, then Grand Total on a separate sheet.
