Returning multiple values using multiple matching criteria

Question

I have a table with three columns. The column headers are thus: Customer, Event, and Owner. I want to enter a "Customer" and "Event" value in reference cells and have the formula return a list of all the "Owner" values that match the Customer and Event criteria.

I have a formula that filters on one criteria and returns a list of all matches (F1 is my reference cell):

=IF(ISERROR(INDEX($C$1:$C$6,SMALL(IF($A$1:$A$6=$F$1,ROW($A$1:$A$6)),ROW(1:1)),1)),"",INDEX($C$1:$C$6,SMALL(IF($A$2:$A$6=$F$1,ROW($A$2:$A$6)),ROW(1:1))

I have a formula that filters on two criteria, but only returns the first match (J1 and J2 are my reference cells):

=INDEX(C2:C6,MATCH(1,(A2:A6=J1)*(B2:B6=J2),0),1)

I need help combining the two formulas so that I can both filter on two criteria and return all the matches in a list. I tried adding a second criterion to the IF statement nested in the SMALL function of the first formula, but it doesn't seem to work.

Answer 1

It is hard to know what you need without seeing the data, but please give this a go.

This is an array formula and must be confirmed with Ctrl + Shift + Enter .

=IFERROR(INDEX(C$1:C$11,SMALL(IF((A$2:A$11=J$1)*(B$2:B$11=J$2),ROW(A$2:A$11)),ROW(1:1))),"")

After confirming the formula you can then copy it downward.
