Reporting custom fields

[Miguel Angel Salas Solis]

Hi, I would like to know if this is possible:

For Instance, I have 20 Payroll tickets, 8 of them have "0" in the # of Errors field, and the other 12 have distinct values on the # of errors field such as "5", "20", "8", etc.

And so far I'm only able to pull out a graphic that would tell me that I have 8 Payroll tickets with no errors and 12 with errors, but what I need to know is the total of errors of that 20 tickets, let's say: there were 158 errors on those 20 tickets.

Is this possible?

Thanks in advance
