=SUMIFS({GM Compliance Trained}, {GM Compliance Training Dept}, Department@row , {Compliance Training Date}, MONTH(7, 8, 9))
GM Compliance Trained is the number of employees trained.
I am trying to sum the number of employees trained in each department during 3rd quarter (July 1-Sep 30). Thinking I need an IFERROR in there but not sure where.
Any help would be very appreicated.
