Column E is a weekly subtotal columns where i have manually calculated the subtotal for two weeks, can i have some formula that can drag down and calculate the subtotals

Hi,

pls try

as Array formula (Ctrl-Shift-Enter)

=SUMPRODUCT(($C$2:$C$1500),--(CEILING(($A$2:$A$1500-DATE(YEAR($A$2:$A$1500),1,1)+WEEKDAY(DATE(YEAR($A$2:$A$1500),1,1),2))/7,1)=WEEKNUM(F8,2)))+SUMPRODUCT(($D$2:$D$1500),--(CEILING(($A$2:$A$1500-DATE(YEAR($A$2:$A$1500),1,1)+WEEKDAY(DATE(YEAR($A$2:$A$1500),1,1),2))/7,1)=WEEKNUM(F8,2)))

Thing is Rgonzo, you have put that into the cells where Sunday is adjacent, whereas i need to put formula into E2 and drop down, so it is automatically finding sunday and returning a subtotal for previous week or remaining blank if not Sunday

Do you want to the last total

=IF(MAX(F3:F1500)=0,"",SUM(--($F$3:$F$1500=MAX(F3:F1500))*IFERROR((E3:E1500)*1,0)))

in Sheet Sales 2 formula without helper's formula

BTW

Corrected Formula  
=IFERROR(SUMPRODUCT(($C$2:$C$1500),--(CEILING(($A$2:$A$1500-DATE(YEAR($A$2:$A$1500),1,1)+WEEKDAY(DATE(YEAR($A$2:$A$1500),1,1),2))/7,1)=WEEKNUM(F8,2)))+SUMPRODUCT(($D$2:$D$1500),--(CEILING(($A$2:$A$1500-DATE(YEAR($A$2:$A$1500),1,1)+WEEKDAY(DATE(YEAR($A$2:$A$1500),1,1),2))/7,1)=WEEKNUM(F8,2))),"")

Hi Rgonzo,

I want to put a formula in E2 and drag all the way down. When the formula sees that its corresponding value in B = Sunday, it needs to create a subtotal for the previous 7 days sales summed.

So with the data i have provided, it would look like my attached ss in tab sales

But i need to be able to have the formula already in the ss so it doesnt need to be manaully added

Hi,

pls try in E2 and fill down

=IF(B2="Sunday",SUM(OFFSET(C2,-6,0,7,2)),"")
