Hi Excel Peoples

I've got a table with dates as headers and I want to sum up the values under those dates depending if they fell under this week or last week.

If I create new rows that use Weeknum() to specify that weeknum value for the date in question and the current date the sumif works fine

I'm trying to make the formula more efficient and eliminate the need to create more rows of data I only need temporarily. I've tried the following but neither work.

=sumif(E4:X4,Weeknum(4:4)=Weeknum(TODAY()),E5:X5) results in = 0
=sumif(Weeknum(E4:X4),Weeknum(TODAY()),E5:X5) results in = 0

Any recommendations on how to tweak this so it functions as expected?

Thanks

Don't think that weeknum works with an array unfortunately

Why not just use sumifs and define it to sum between the dates that makes the desired week? So if you want to sum the current week you use today inside weekday and then subtract that from today to get the start of the week. Then you can define the end of the week by adding 5 or 7 days. Then you use these dates as the criteria in the sumifs. Quite simple and efficient

thanks for the recommendations! I got it to work!

=sumifs(D5:W5,D4:W4,">="&today()-weekday(TODAY()-1),D4:W4,"<="&today()+(7-weekday(today())))

Great! For future reference I think your first solution might work if you use sumproduct instead of sumifs.
