Hi,

I am currently using Excel 2013 Professional but I want to be able to use the same formula in a Google Spreadsheet. Basically, the formula I have in Excel is this:

=SUMPRODUCT(--(INT((Sheet1!$U$2:Sheet1!$U$1500-DATE(YEAR(Sheet1!$U$2:Sheet1!$U$1500),1,1)-WEEKDAY(Sheet1!$U$2:Sheet1!$U$1500))/7)+2=H1),Sheet1!$AH$2:Sheet1!$AH$1500)

Column U represents dates.
Cell H1 is the number of the week (1-53) and column AH is the amount invoiced. 
The formula returns me the sum of all invoices for the week number specified in cell H1. All other invoices that don't have a date within the week number specified in cell H1 are neglected. 

Thank you.
Eduard
