If you mean *criteria* when you say arguments, the best
you could do would be something like:

=SUM(SUMIF(A:A,{"a","b","c"},B:B))

This would sum for all 3 conditions. But it's not very
robust. Your best bet would be SUMPRODUCT:

Any idea how you can enter three arguments into the
SUMIF function?

Many thanks
