The best way would be to eliminate the NA's. For instance, if they're
generated by a VLOOKUP(), trap the "match not found" error:

=IF(ISNA(MATCH(A1,J:J,FALSE)),"",VLOOKUP(A1,J:K,2, FALSE))

But you could also use this (array-entered: CTRL-SHIFT-ENTER or
CMD-RETURN):

=SUM(IF(ISNA(B1:B100),,B1:B100))
