9 3 Services
12 2 Services
15 3 Contract

17 3 Goods

Ledger

I have a journal file and a ledger.
The journal contains expense category, date, value and is
randomly
sequenced.
The ledger is a rectangual array. Rows are expense categories,
columns are
months. The leger cell for a given expense category / month is
the
sum of
journal entries with the given expense category and month. I have
a
feeling
that Is hould be able to use something like DSUM to do this, but
I
can't
figure it out. I'd appreciate suggestions! I daresay many people
have
done
this, so a reference to a solution would be fine. I don't, of
course,
have
money to solve the problem... or someone else would be doing it.

Thanks
