I've never seen this.

Are you sure that you don't have more rows that go into that sum than you think?

I have an excel spread sheet with negative and positive numbers and when I
do calculations in excel, the negative numbers are subtracted from the
positive numbers for a total. However, when I try to use a pivot table, 2
negative numbers are added together and reported as a positive number. How
can I get the negative numbers to subtract in a pivot?
