I have a spreadsheet that I use VLookup to find a Person's scores
based on Month. However, I have to change the reference number in the
VLookup manually in order to get my results.

I use column number 28 for April, column number 57 for May. I was
using a very basic formula that got me by using IF/Vlookup for April
alone, but now that it's May, I had to change the column number
manually.

I tried this formula, but it seems that you can't nest a Vlookup
inside a Vlookup! :)

=VLOOKUP(CONCATENATE($A14,C$13),'2007'!$B:$AC,(VLO OKUP(E2,AZ:BA,
57,FALSE)),FALSE)

Help would be greatly appreciated!! :) Thanks for your time & efforts.
