Works the same in both versions for me. Are you sure the "x" is the only
entry in the range? Might there be formula blanks?

Use this instead:

=INDEX(X11:X15,MATCH("x",Y11:Y15,0))

I am using a reference shown here =LOOKUP("X",Y11:Y15,X11:X15) to find a
number in a column to the right of an "X"


0
X 1
2
3
4

In this example the x is next to the number 1, and should return that
value-
however in 2007 excel it seems to show the value 4 when the x is next to
the
2 ( or at least some other number).

Thoughts ideas?
