Hi wrighty50,
Pecoflyer didn't like the "False" because the MATCH() function is looking for a -1,0 or 1 for the third argument. Your "False" in your CF formula will translate to a zero and all if fine for an exact match. So you can use a zero or False in your case.

I'll look at your new attach file now but wanted to get the False vs Zero partial question answered first.
