I have a report that is grouped by workers in the company and then each day of the year. The report shows if the worker came to work or was absent. field is either showing an A or a B. I am using a running total to count the number of times A appears, and reset the count when B appears. The issue is that the running total needs to reset when the group changes (to the next worker). How can I write a formula that will reset on either Field change or group change?
