This is helpful and I will think on this, but in my case nearly all of the
CountIfs will be greater than 1. To use your example, I may have 10
instances of "Joe" in my list; the lookup against "Joe" might return "abc" or
"cde". Most Joe, Pam, etc. have only one value "abc" as their match, but
some Joe, Pam, etc. have both "abc" and "cde". I need a way to know that.

will give you the count if there are more or fewer than one.
Otherwise, it performs the lookup.

I am using LOOKUP functions to retrieve info from a list. Some of the lookup
values have more than one match in the list. Is there a function that allows
me to retrieve multiple elements for one lookup value, or at least a function
that tells me there are duplicate matches?
