You need a group footer. Currently you have table footer which shows grand total.
REccCt and set the expression as =SUM(Fields!REcCnt.Value)If you don't want to show the grand total 37 you can delete the table footer not the group footer you just created.
Update Reread your question. You also need a group header along with group footer.
