I need help Suming up Amount column based on values of three different
columns.

Let's say I have the following Detail Data:

Month Institute Account Type Amount Memo
1/1/2008 Bank of America Checking 500 Deposit
1/1/2008 Bank of America Checking -200 Check #111
1/1/2008 Bank of America Saving 400 Deposit
1/1/2008 Bank of America Saving 150 Deposit
1/1/2008 CitiBank Checking 50 Deposit
1/1/2008 CitiBank Saving 100 Deposit

How can I SUM the AMOUNT column based on the unique values in the Month,
Institute, and Account Type columns?

The Summary result I am hoping for is:

Month Institute Account Type Balance
1/1/2008 Bank of America Checking 300
Saving 550
1/1/2008 CitiBank Checking 50
Saving 100


I have been trying to resolve this issue and I am stuck! Any help would
be
highly appreciated.

Thanks in advance
