Thanks, your 2nd formula did exactly what I needed.

I am using this CF to find my duplicates =COUNTIF(A1:A$10000,A1)1. The next
part I need is to count the number of duplicates (gray shaded &
strikethough). I have tried a few VBA but I read they don't work with formula
based CF's.
I could also sort the gray shaded then count them with a helper column but
ideally would be have one cell at the bottom of my 8000 rows that total my
duplicates.
