I have a repeating group with two number fields in each row… I want to take the sum of each field in the repeating group… No problem… However, I then want to subract the two sums from each other… So I took the formula for each sum and put a minus sign between them such as

Inc Stream Repeating Group’s List of IncStreamGets’s Monthlyincome:sum - Inc Stream Repeating Group’s List of IncStreamGets’s Monthlyexpense:sum

Problem is that it is interpreting the minus sign as a character and just putting the first sum then a ‘-’ then the second sum… How can I get these two to subtract correctly?
