sumifs function combined with NOT

Hi I try to set up a formula the first part is working. But now I try to exclude the not briefed articles in column (active article check).

What needs to be adjusted that below formula is working?

Thanks

=SUMIFS([shipped quantities in pairs]@row, [Article#]@row, CONTAINS([Article#]@row, @cell, [active article check]@row, NOT(@cell = "not briefed")))
