sumproduct help

[Guest]

I need to sum a column if numbers that contains many #n/a returns. I was
thinking of the sumproduct formula but I can't figure out how to get it to
ignore the n/a's.

something like SUMPRODUCT(--(ISNUMBER(F3:F610)),F3:F610)

How do I do this?


Thanks

Try

=SUMIF(F3:F610,"<>#N/A")

or to ignore any error values

=SUM(SUMIF(F3:F610,{"<0",">0"}))
