I've a Report with two group-footers. The inner footer includes [price] and an expression =sum([amount]). I've added an additional expression to this footer, as follows: =[price]*[txtSumAmount], where txtSumAmount refers to the '=sum([amount])' Text Box. This works fine. I now need to add another Text Box to the outer footer, that sums the 'price * txtSumAmount' expression. I've tried several variations. How can I sum up the subtotals obtained in one footer to obtain a grand total in the other footer?
