Is there a way to use Vlookup but have it return the sum of multiple cells. For instance if you had Jan, Feb, March, etc in A1:A12, with corresponding cash flows in B1:B12, I want my lookup formula to look for a month, say March, but return the sum of the values in the 2 months leading up to March as well (B1:B3) rather than just return the value in cell B3.
Is that possible? Thanks
