Heres the record ID 2003001 A 12.9 B 15.4 C1 12.5 D1 10 C2 Null D2 12.9 Given the above how do I get a count for ID 2003001 of 5 indicating that the student sat 5 exams out of the possible 6. The Null indicates that the student did not sit that exam. Not my DB and I cant change anything re structure etc Martin
