=SUMPRODUCT(--(A1:A9B1:B9),(D19))
The first part, --(A1:A9B1:B9), generates a series of 1's and 0's, with the
1's where your condition is satisfied. The second part (D19) is the series
of values you want conditionally added. Sumproduct multiplies corresponding
components of the two series and adds the results.
