I am trying to use a SUMIF function to add figures from column A when the
corresponding entry in column B (which is a date) is less than a year ago.
To try and make things easier I have a formula in c1 which carries out the
date calculation =TODAY()-365. I have tried various formulae but have not
been able to achieve a successful result - my latest effort is
=sumif(b:b,c1,a:a) and I have also tried =sum(if(b:bc1,a:a,0)). Can anyone
help ?
