Sum lookup values using SUMIF

To sum values retrieved by a lookup operation, you can use SUMPRODUCT with the SUMIF function. In the example shown, the formula in H5 is: =SUMPRODUCT(SUMIF(codes,C5:G5,values)) Where codes is the named range J4:J5 and values is the named range K4:K5. Context Sometimes you may want to sum multiple values retrieved by a lookup operation. In this example, we want to sum holiday time taken each week based on a code system, where F = a full day, and H = a half day. If a day is blank, no time was taken. The challenge is to find a formula that both looks up and sums the values associated with F and H.
