I am creating a high level sheet with only weekly totals. I want to sum by week the 3 columns highlighted in yellow that are not next to each other in the same sheet (example only). The Week column is a formula =IFERROR(WEEKNUMBER(Date@row), "") .
This is the formula I have tried I get error: Incorrect Argument Set.
=SUMIFS({Week}, 27, {Copywritten}, {Copyedit}, {Copyproof})
When I try it with only one column say the copy written one the formula works, but when I add the other two columns it doesn't work.
I then tried this still same error.
=SUM(SUMIFS({Week}, 27, {Copywritten}, SUMIFS({Weekof}, 27, {Copyedit}, SUMIFS({Weekof}, 27, {Copyproof}))))
