I have a workbook with multiple wooksheets. On worksheet 1 F1 is a month/yr.
ie. Feb 08 (text). I want to do a Vlookup on E6 to sheet '2008 Budget' and
sum columns up to column labeled Feb 08. Next month I will want the sum of
Jan 08, Feb 08, Mar 08. etc. Each month adding a column to the sum.
Looking at the following formula I want it to return the sum of B:M up to the
column matching the value in F1.

=VLOOKUP(E6,'2008 Budget'!$A$1:$M$105,('2008 Budget'!Sum(B5:C5)),FALSE)

Can this be done?
