Hi Bernie
correct. Good spot.
Thanks for this formula though should go to Aladin (at least I think he
was the first one who posted this LOOKUP formula type)

Note: This formula is also quite slow. So if The OP only has numeric
values to look for he may also try:
=LOOKUP(9.999999E307,2:2,1:1)

Cool formula, Frank. The OP would need it to be

=LOOKUP(2,1/(2:2<""),1:1)

I have columns of data starting from Jan 2002 thru Sep 04 (33
columns)
Data contains numbers or are blank
Is there any formula (other than a VBA) that can determine
against
each row
the last month I had any number
Example:-

Jan-00 feb-00 mar-00 apr-00 may-00
50 12

The result should be Feb-00 as that month is the last time when
I
had a
data (and not blank) looking from right to left.
Just the formula to determine the column # will suffice, using
offset
I can
determine the month.
