问题
I have an issue with a vlookup/index-match formula in excel 2010.
I have a table that contains duplicate values in the name column. I have a table in another sheet that reference the name & amount from the first sheet. in case a duplicate name exist in the original table, it should sum the amount.
For example, look at the pic below. ABC is a duplicate name, and it's amount should be zero. How can I use Vlookup/index-match formulas in order to display "0" in the result when I lookup the name ABC?
In the destination sheet, the name only appears once, hence I don't want to add another ABC to the dest table.
Thanks !
Roni.
回答1:
VLOOKUP and or INDEX/MATCH will only return you one entry (the first match) - so you cannot use it for summing (unless in an array formula).
However, using SUMIFS (or in Excel 2003 and earlier SUMIF) will be just what you need: So In F2, you could write:
=SUMIFS($C$2:$C$6,$B$2:$B$6,E2)
