If I open a new workbook, format column A as currency, and enter this: A1: 522.25 A2: -4378.87
Then go to another cell, and enter this formula: =(A1+A2) My result is 3856.62, as expected. You are adding a negative to a positive. You'll get valid results. Perhaps there's a cell format issue that isn't recognizing the negative numbers somehow? *********************** Charlie Kaiser [email protected] Kingman, AZ *********************** > -----Original Message----- > From: John Aldrich [mailto:[email protected]] > Sent: Tuesday, June 29, 2010 9:29 AM > To: NT System Admin Issues > Subject: RE: Excel question > > I don't think so.
