I have seen the answers to similar questions which suggest the use of
SUMPRODUCT. I have also seen mention that this works for exact and equal
ranges, but i need to do this for columns, because i will be continuously
adding to the ranges.

My columns are named ranges (month, fce1A, SpEE). Here is the sumif
statement.

=SUMIF(AND(month = "Mar 2006", fce1A = true),true,SpEE)
