I have 2 columns L and N that have payment dates in them, I need a formula
that will scan those 2 columsn because the payments are made in 2 equal
payments and add everything from another column into a cell made for that
date. adds everything together-sumif is working fine with only one column of
dates, but with 2 columns, some strange additions are happening. Any help is
appreciated.
