I have a Profit & Loss budget vs actual report that I run by class.  I am including the subcolumns for showing actuals $ difference and % of budget.  When I export the report to excel, some of the classes have the $ over budget exporting as a formula (which is what I want) and others only export that column as a number.  What's going on and how can I make it so that ALL of the classes export that column as a formula?
