Vlookup updates

[Guest]

I am trying to vlookup data in column X based on a particular month eg
December.

Is that possible?

Month x Data
Mar-06 1 100
Apr-06 2 51
May-06 3 497
Jun-06 4 494
Jul-06 5 0
Aug-06 6 10
Sep-06 7 197
Oct-06 8 495
Nov-06 9 700
Dec-06 10 747
Jan-07 11 660
Feb-07 12 542

Hi!

Try this:

A1 = Lookup_value = December

Formula needs to be array entered using the key combo of CTRL,SHIFT,ENTER:

=INDEX(C2:C13,MATCH(A1,TEXT(A2:A13,"mmmm"),0))

Here's another way as long as there is only one entry per month (as in your
posted example):

Normally entered:

A1 = December

=SUMPRODUCT(--(TEXT(A2:A13,"mmmm")=A1),C2:C13)
