Hello,
If your statements were converted from DOS, then you should "clean them up" by following the step by step instructions

The financial reporter is a spreadsheet just like Excel, and you tell it to add up a column of numbers using either SUM(), VSUM() or a+b+c+d etc...
If you need basic training on the financial reporter, you can sign up for a webinar
here (there's a Basics class on the 13th) or you can contact your local Adagio Partner who can help you.
