Hi Yogi,

Thanks again for explaining how this works, I really appreciate it.
However I ran into a problem in using the formula.  My actual dataset has 500+ rows.
The formula currently requires that I copy it for each of the rows.  With 500 rows, this becomes infeasible as it takes too much time.

Is there a way to do function for multiple rows all in one iteration?
I set up a test sheet here to explain it a little better.

Thanks
