The most common reported problem is that the worksheet is not calculating or “#VALUE!” appears in many of the cells. If this seems to be your problem, check to be sure that Macros are enabled. Our spreadsheets utilize VBA function subroutines and Macros must be enabled for them to work. You need a Windows computer with Excel 97 or later, or a Macintosh with a pre-2007 or post-2015 version of Excel that includes VBA. Our software does not function on other spreadsheet programs.
