In this case I'm using the header rows as the range of return values even though I'm searching through lower rows.
This is useful for finding the first entry point for a person attending a class, or a character in episodic tv or movie franchise.
So let's say my column headers are the Fast & Furious movies (with Fast 9 in the leftmost column and the first movie in the rightmost column, and my rows are the character names.
For Dom, I can put his row values under most of the movies as "Lead" and can put "Cameo" for Tokyo Drift. Using the formula above, it will return "The Fast and the Furious" (his first movie rather than "Lead")
