hi,

i have columns of data in my sheet, for 2008, each with a column heading in
the MMM-YY format. my formula worked for all months in 2008, but now that we
have transitioned to 2009, it is not adding the values columns for the months
in 2008. here is my formula:

=SUM(OFFSET($A$1,ROW()-1,MATCH(DATEVALUE("Jan-"&TEXT(YEAR(TODAY()),"YY")),$1:$1,1)-1,1,1):OFFSET(BO2,0,0))

i am not sure how to amend this formula so it works this month...

thanks in advance,
geebee
