Help with a report

[Faria]

Hello,

Maybe someone can help me with a report.

As you can see in the following image, I have 2 issues. 

1- I want to get all the percentages that exist from a certain user in only one line. Its creating multiple lines for the same person and then each one with a diferent percentage. I want one line for the name, then a line for the percentage, and every line corresponding to that percentage. Then another percentage, and all the values of that percentage. and only then it goes to the next user.

2- I created a field that is a calculation of the amount * percentage. But its always nil. The numbers are set and saved in the database but I cant get a simples field with the result of that calculation.

Thank you for your time.
