OK - I'm sure I'm missing something simple here BUT.....
is there a way to see the total of how much I earned last month on CS?

?
If I go to Statistics and run a report, download it into Excel, I still cannot see any totals - nor add them up myself due to the format. (For the current year anyway it's fairly hypothetical because, just to add to the fun, 2014 is not yet an option for any report yet!)
The only solution I can see is to get my trusty old calculator and sit there manually inputting and adding...
Often, sales are so few, it's not a big problem.
BUT I'm guessing I'm missing something REALLY OBVIOUS!
Please can anybody help?
