counting records per group

Question

I have 3 group fields in my report, my details section only contains 1 field of data, I tried creating a formula with count() to count the number of records in the details section but it counts everything, how do I get my formula to consider the groups?

Answer 1

Place field into details section, insert summary (count) field into correct group header/footer, delete field from details. Done :)

Of course you can use formula too - aggregate formulas (sum etc) can have second parameter to specify grouping level.
