where “code” is the named range K5:K9, and “value” is the named range L5:L9. Note: this is an array formula, and must be entered with control + shift + enter. which would return 4. The twist in this problem however is that we want to translate and sum a range of text values in columns C through G to numbers. This means we need to provide more than one lookup value, and we need INDEX to return more than one result. The standard approach is a formula like this: After MATCH runs, we have an array with 5 items: So it seems INDEX should return 5 results to SUM. However, if you try this, the INDEX function will return only one result SUM. To get INDEX to return multiple results, we need to use a rather obscure trick, and wrap MATCH in N and IF like this: This effectively forces INDEX to provide more than one value to the SUM function. After INDEX runs, we have: And the SUM function returns the sum of items in the array, 10. For a good write up on this behavior, see this interesting article on the EXCELXOR website.
