Brian,

If your data are sorted you can use

=INDEX(M10:M150,COUNTIF(M10:M150,"<"&24.5)+1)

If it isn't sorted then this ARRAY formula

=INDEX(M10:M150,MATCH(SMALL(M10:M150,COUNTIF(M10:M 150,"<"&24.5)+1),M10:M150,0))


This is an array formula which must be entered by pressing CTRL+Shift+Enter
'and not just Enter. If you do it correctly then Excel will put curly brackets
'around the formula {}. You can't type these yourself. If you edit the formula
'you must enter it again with CTRL+Shift+Enter.

When competing hypotheses are otherwise equal, adopt the hypothesis that
introduces the fewest assumptions while still sufficiently answering the
question.

I am trying to use the lookup function to return the next value greater than
the lookup value in a vector. However, the only thing that the lookup

there a way to get it to return the value greater than.

I am using: LOOKUP(25.4,M10:M150,M10:M150)

...and want to return the first value greater than 25.4 in the vector M10:M150
