Crystal Reports Record Count

Message

     I have created this report that gives me a total number of records by group in an Aged bucket of 0-30, 31-60, 61-90 and over 90. Some Age buckets do not have any records in them so it is blank.  When crystal goes to count the record it is counting all the record for that group.  See example below of what crystal is doing. It is counting every record instead of the record with a positive number. I want to count the number of record in say 0-30 should be 10, 31-60 s/b 5, 61-90 s/b 1 and over 91 s/b 3

Is there a way where i can have crystal count the records like it would count the record in excel and not include blank spaces.

Thank you very much.
