I found the solution.
We have to create two variables N1 and N2 with these parameters:


N1 N2
__________________________________________________________________
Value to store: 0 iif(N1=1,1,0)
Initial value: 0 0
Reset at: "name of the group" End of Report
Calculate: Count Sum
__________________________________________________________________

Variable N2 is what we need.


Interesting, isn't it.
