Excel 2007 if range = A2 vlookup

Question

I want to know the month when the price of an item matching A2 was the lowest. how can I do a vlookup on only the items where column B = A2?

Answer 1

To return month where price is lowest for product from A2, use this array formula (if there're more then one month with lowest price - formula will return first one):

=INDEX(F:F,MATCH(MIN(IF(B:B=A2,E:E)),IF(B:B=A2,E:E),0))

note, since it's an array formula, you should press CTRL+SHIFT+ENTER to evaluate it
