I know this should be simple, but I can't get it to work. I balance grants and I want column C to be the amount of monies expended during a particular month. C7 is salary, C8 is travel, C9 is supplies ect. I want column D to automatically increase by the amount I put into column C - or to the the cumulative amount spent. I want D7 to reflect the past expenditures plus the monthly expenditures, to show the cumulative amount spent on that line item from the beginning of the grant. Can this be done?
