The 0 at the end makes the Match() function look for exact matches *only*.
When looking for exact matches, the lookup data table does *not* have to be
sorted, and since yours (Column B) is not sorted, it returned the correct
value.

Thanks so much, it worked great. The ,0)) at the end makes all the
differance, but why?

This is probably easy one but I cant figure it out.
I want to get the field name/label from the same row in the column to
the
left of the result of a MAX or LARGE function. Tried LOOKUP but data is
not
in order.

e.g.

A B
ReasonA 23
ReasonB 44
ReasonC 17 I would like MAX function to return 'Reason B'
