>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?

It should be

vfp.SetVar([nUnSt], nUnSt + 1)

It can also be done with Report Variables. Try

Variable: rnLines
Value to Store = 0
Initial Value = 0
Calculation Type: Count
Reset At:Group: Student

Variable: rnUnSt
Value to Store = IIF(rnLines=1, 1,0)
Initial Value = 0
Calculation Type: Count
Reset At:Group: Tutor
