Hi - I'm using 8.5, and I have a running total field that calculates the difference (DIFF) value between 2 numeric fields in the database. This DIFF is displayed once on the report for every account # in the database. That is fine, but I want to include a grand total on the DIFF - and I can't seem to figure out how to do a SUM on this running total field. Is there a way to get a grand total on a repeating running total field? Much thanks!
