No this is not for a class. I'm trying to set up a personal budget. I've tried playing around with WEEKNUM and IF statements, but have had no luck. I've tried the DAYS function, but since it's constantly changing, there is no real end date. That is why I added the "DAY TOTAL" column. My prior attempt was =IF(WEEKNUM(A2,1)=WEEKNUM(A3,1)," ",SUM(D2)). But as the formula moves down the column I don't know how to make it go back to the first day of the week to SUM the total.
