subtotals in reports

[HSalim]

Hello all,
I have a report that has multiple groups. Detail, YearFooter, ProjectFooter
and Department Footer

In the ProjectFooter, I have a text box where I am using a function to
calculate available workdays between 2 dates (Function taken from
http://www.mvps.org/access/datetime/date0006.htm )
Control Source = WorkingDays([ProjStartDate], [ProjEndDate])
Name = txtAvailWorkDays
This Does return available workdays for the project

However, I am not able to get a sum of the available workdays in the
Department footer.
I have a textbox with the control source set to = Sum([txtAvailWorkDays])

When I run the report, txtAvailWorkDays appears as a parameter, and i am
puzzled..
Is it not possible to sum a value from an intermediate footer? If not this
way, is there any way?

Any help would be most welcome. thanks in advance.

Regards
Habib

The aggregate functions only operate on fields in the
form/report's record source table/query, they are unaware of
controls.

You can use:
=Sum(WorkingDays([ProjStartDate], [ProjEndDate]))

Or, you can use a text box with its RunningSum property set
to Over Group to get what you want.

Marsh,
Thanks for replying. I tried using running sums but was having trouble with
getting it to work over multiple groups.
Eventually, I just calculated Working Days right in the query and it works
well enough, for now at least.
I suspect performance will suffer significantly as the database grows.

Yeah, running sums across groups can be a little tricky, but
it can be done ;-)

I should have mentioned calculating the workdays in the
query, which is a perfectly valid way to do it as long as
you're using a Jet database. I haven't tested it, but I
suspect doing it in the query is about the same as using the
aggregate funvtion in the report (maybe even a little
faster), but don't quote me on that ;-)
