I have cells B2, e2, H2 etc calculating % of target achievement that calculates % of target achievement so B2 cell formula is =b24/b4 for sales day 18. Each day i have to manually adjust the formula to reflect the changing day so for day 19 i will have to change the formula to b25/b4. Looking for a formula that would automate this process referencing the sales day in cell A3.

Help greatly appreciated.

Thanks
