Evaluate doesn't equal results

Hello, I am new to Jet Reports 2009 and having a small issue. I've created a cash flow report which works very well, except for the Net Income. I am using the GL function (for NAV 2009) to return the value of my Net Income account, not including closing entries. When I open the function wizard and evaluate the formula, the result is correct. However, when I run the report, I am not getting the correct value. My cash flow has 3 columns of data, one for each of the 3 divisions I am reporting on. Am I doing something wrong?
