I have developed a report in Crystal Report 2008 but When I try to run it, it gives the following error.
I used Calculated members in report and the error come when I try to modify a group within my report.
I tried to solve it and have googled but could find any solution.


There are two possibilities:
1) The column
Favorableis not present in the grid.2) There is a bug in Crystal Reports (not entirely unheard of).
At least one person has recently reported this as an issue when individual rows do not have all of the columns.
