Let say you have a table with columns A, B, C, D, E, F and you want to do a
vlookup, but not the regular vlookup but one that takes into account values
in columns A and B. For instance:

A B C D E F
Day Tue 2 4 3 3
Day Wed 7 6 8 5
Day Thu 2 1 9 7

Taking the 2nd row, I want to do a vlookup based on Day and Wed instead of
just using Day. Is there a function like that or any combination of functions
that I can use to do this?
