Here is the Data I have...

Last_Name, First_Name, Balance, Due_Date
Rich, Joseph, $8000.00, 7/15/2006
Amar, Jane, $6500.00, 3/25/2005
Stine, Richard, $7500.00, 9/15/2006

The first line is the title for the excel cells.

How do I word the formula bar if I would like to get a total balance from accounts that are due from 3/15/05-7/15/2006 and that fall within the alpha of A-K?
