Pivot structure

[piziarl]

Hi there, I am working with Pivot table to manage an activity for a little farm and I have noticed that in the pivot page I got 2 voices “sum of of revenue and sum of outputs”, but in the section of revenue I find also some voices of costs and the same happen under section costs I find some voices of revenue.
The question is: how can I build a pivot table without these mistakes?

Thanks
