Excels INDEX with MATCH for multiple criteria

Question

I am experimenting with excel's functions. Say I have the following example values
Column
A1 - "Andrew"
B1 - "Morton"
B2 - "Andrew"
A2 - "Morton"
A3 - "2"

Why is my formula not printing the output 2?

=INDEX($A$3:$A$3,
MATCH(A1, ($A$1=$B$2:$B$2) * ($B$1 = $A$2:$A$2), 0))

The following prints the correct output 2 with single criteria.

=INDEX($A$3:$A$3,
MATCH(A1,$B$2:$B$2,0),1)

Thanks in advance.

Answer 1

These type of formulas don't work well with single cell ranges, as per your example.

Lets assume first names in A2:A10 and last names in B2:B10 - if you want to find the row which matches both names and return the corresponding value from C2:C10 you can use this "array formula":

=INDEX($C$2:$C$10,MATCH(1,($A$2:$A$10="Andrew")*($B$2:$B$10="Morton"),0))

confirm with CTRL + SHIFT + ENTER

....or you can add an extra INDEX function to avoid array entry

=INDEX($C$2:$C$10,MATCH(1,INDEX(($A$2:$A$10="Andrew")*($B$2:$B$10="Morton"),0),0))
