Change the PivotTable name to: AcademicPivotTable
B. Add the Activities field and the Group Name field (in that order) to the Rows area.
C. Add the 2021, 2022, and 2023 fields (in that order) to the Values area.
D. Change the display of subtotals to Show all Subtotals at Top of Group.
E. Change the report layout to Show in Outline Form.
F. Update the Sum of 2021 field in the values area to display the name 2021 Membership with the Number number format with 0 decimal places.
G. Update the Sum of 2022 field in the Values area to display the name 2022 Membership with the Number number format with 0 decimal places.
H. Update the Sum of 2023 field in the values area to display the name 2023 Membership with the Number number format with 0 decimal places
