How to print current total in the column footer of

问题:

I am designing a report the for the ledger used in accounting. At the end of each group, I have to print the total. For that I can easily do it using the group footer. But when the group is large, it spreads over many pages. The problem is that in intermediate pages there is no total, but only in the last page.

How can I print current total in the column footer of each intermediate page?

Is there any tag or way that I can use in the Print when expression to do this?
