Hello. I'm trying to figure out how to look up a value based on (a)the customer name and (b) the year. There are multiple years for each customer. So, if customer=ABC client and year is 2008, then find that intersection in the data table. But, if year is 2009, 2010 or 2011, I want to add the ability to look at each year for that client and pull the right value. I've tried INDEX and MATCH and VLOOKUP, but can't figure out how to nest an IF statement in them.
Really need help with this one!! Thanks much!
