Wrong totals in report

[Guest]

I built a report based upon a query that joins two tables: 1) has vendor name
and the total spent on that vendor, and 2)has contract details. My problem:
when there are multiple contracts with a single vendor, the vendor name and
the amount spent prints for each contract, thus throwing off the totals for
each contract class. How can I fix this?

Your problem is that you are storing calculated data -- "total spent on that
vendor"
Store each contract cost with the contract information and not store total
any place. Calculate it when you need it.
