Running sum in group header

[Access User]

I'm trying to print totals in a group header section on a report, but I'm
not getting the results I'm looking for. I have two hidden counters in the
StudentID_Header_Section--one keeping a running sum over the group, and the
other keeping a running sum over all--but I want to print the group sum in a
previous header. The grand total is correct, but the total printing in the
previous group header is incorrect. What am I doing wrong?

Here's the report design:

School_Name_Header_Section
[School_Name] [Total_Students]
ControlSource:
=[RunningSumOverGroup]

StudentID_Header_Section
[RunningSumOverGroup] [RunningSumOverAll]
ControlSource: =1 ControlSource: =1

Report_Footer_Section
[Grand_Total_Students]
ControlSource:
=[RunningSumOverAll]


Here's the report output:

School_A Total Students: 1
Student 1

School_B Total Students: 1
Student 2
Student 3

School_C Total Students: 1
Student 4

Grand Total Students: 4

Thanks for any help,
Alec

I think they change that so it would work in A2003. I have
no idea how they could display a value that has yet to be
calculated so my confidence level in its reliability is low.

OTOH, I don't see why you would need a running sum just to
count the records. Can't you use the report and group
header text box expression =Count(*) to do what you want?

Thanks for the reply. Actually, there's a bit I didn't mention about the
fact that there could be multiple detail records for a student (e.g. one
student could be in multiple classes) that would throw off a count of unique
students for each school.

Looks like I'll just stick the subtotal at the end of the group and live
with that. Thanks again for the help.
