I am wanting to do a percentage on sums in a group. I have multiple groups, that have sums (subtotals) within those groups. Right now I only have percentages at the end of my report. Example: Sum ({ARCUSFIL_SQL.amt_age_prd_1}) % Sum ({ARCUSFIL_SQL.balance}) How do I tell Crystal 8.5 I want to perform a calculation on sums that are scattered throughout the report. Thanks in Advance
