Help with SUMIF function criteria
I am trying to sum column I based on the rows that do not have either Jason
or Michael in column D.
=SUMIF('Master Client List-do not edit'!D:D,"<Jason""<Michael",'Master
Client List-do not edit'!I3:I65535)
However, the above formula is giving me the results number of unique #rows
not equal to Michael and #rows not equal to Jason (i.e. all rows because it
sees it as an OR rather than an AND).
What is the correct formula?
