Here is the query I came up with:
SELECT Sum(Invoices.Amount) AS SumOfAmount, SubAccounts.AccountType
FROM Invoices, SubAccounts
WHERE (((Invoices.Date)>'6/30/00' And (Invoices.Date)<'8/1/00'))
GROUP BY SubAccounts.AccountType;
However, it doesn't work at all.  It seems to be ignoring the "WHERE" clause
and adding together every invoice ever produced.  Any suggestions would be
appreciated.
SumOfAmount           AccountType
