Works perfectly and I don't have to change my format for the accountant. Thank you sooo much.In "C12"
=SUMPRODUCT((Sheet1!$B$3:$B$10)*(Sheet1!$C$3:$C$10=Sheet2!$A12)*(MONTH(Sheet1!$A$3:$A$10)=MONTH(Sheet2!C$2&0)))
Looks loads better than mine. Not sure what I was doing wrong. CheersIs this too messy?
