=COUNTIFS({Staff name}, ="Kyle Black",({Date Completed}, AND(@cell <= TODAY(), @cell > TODAY(-7))))
or
=COUNTIFS(Staff name:Staff name,"Kyle Black", [Date Completed]:[Date Completed], and(@cell >= TODAY(-7),@cell <=Today()))
One of these i got from customer service and the other i found on a post here. I don't know if i am typing something wrong or what the issue is
Both send back #unparseable
