So it sounds like you want a total of these two fields combined? This would only make some sense if the v_surgeon field was sometimes null. Assuming it is, you could use a formula like this for the grand total (in the report footer):
count({table.v_surgeon})+sum({@total_endo_cases})
A group level formula (in the group header or group footer) would look like this:
count({table.v_surgeon},{table.groupfield})+sum({@total_endo_cases},{table.groupfield})
I'm wondering whether you should modify your endo formula. If the field can be null, you should change your formula to:
if isnull({v_CRA_21_Endoscopy_Billing_Summary.anesthesia_used}) or
trim({v_CRA_21_Endoscopy_Billing_Summary.anesthesia_used}) = "" then
0 else
if({v_CRA_21_Endoscopy_Billing_Summary.anesthesia_used}="Y") then
1 else
if({v_CRA_21_Endoscopy_Billing_Summary.anesthesia_used}="N") then
1 else 0
