Crystal Reports Last row won't print completely

Message

Hello!It's my first post in this forum!
Thanks in advance for the help.

I have a little problem with a report i'm doing.
The last row in the report won't print in the report.
It only prints String values, but won't print currency values.
I have grouped the results by salesman, country and date

something like this

Code          Name            Country              Invoice           SalesOrders

001          Alexis A.             CO                 1,253.03$          12,546.02$
002          Alexis C.             CO                  

                                     Total                  1,253.03$

the cliente code 002 has an invoice balance, but it won't print it, and it wont add it
Any ideas?
