I've already seen a lot of topics about my problem, but I can't resolve it. Actually, I don't understand what is wrong in my formula ?
=ArrayFormula(
IF(
ISBLANK(A6:A);;SUMIFS(
Sheet1!J:J;
Sheet1!K:K; ">="&A6:A;
Sheet1!K:K;"<="& EOMONTH(A6:A;0)
)
)
)
What I'm trying to do : Each line is a month. I want to SUM all sales made between the first day on the month, and the last one.
If I don't use ArrayFormula, it works. I dont understand how to write this formula to work with ArrayFormula.
Thank you very much for your help !
