A great deal of information can be found by clicking the Show Details button.
The details in this screen should tell you which control on the report is having an issue. The issue could be with the way the report is designed/set up, or it could be with something in the student’s data.
Try narrowing down the list of students so that you can tell exactly which student’s data is causing the error before informing your division support or Maplewood’s support department.
