Thanks. That's an interesting solution. I tried it but I keep getting .F.! I added a new variable to the report and called it nUnSt (for Unique Student), then in the Student's group footer band I added "_vfp.SetVar([nUnSt], nUnSt = nUnSt + 1)" in the "On Exit" expression. Finally, I added a field in the Tutor's group footer to show nUnSt. When I run the report the value there is always .F. Any ideas?
