Hi Ron,

Thanks very much for reply and further input.

The issue must be data related. Are there Blanks? Text?
No Blanks, text only in Row "1" .

Those are the only exceptions that throw errors in my testing.

With the data in A2:H11, this formula is durable against blanks, but not text

No text, although I did have a problem copying back my original Sample Data
using Data Text to Columns which created the #N/A errors but sorted now.

However, regarding my Sample Data and the Expected Results, I've noticed that
your Formula picks out Numeric Value 102 as a consecutive duplicate value in
the SAME column. It is a duplicate in the same column but NOT a consecutive
duplicate as described in my original post. It should not be included in the
results.

A11:
=LARGE(INDEX((FREQUENCY(($A$2:$H$8+COLUMN($A$2:$H $8)*1000),($A$2:$H$8+COLUMN($A$2:$H$8)*1000))1)*R OW($A$1:INDEX($A:$A,ROWS($A$2:$H$8)*COLUMNS($A$2:$ H$8)+1)),0),COLUMNS($A$11:A11))

Does that help?
or.... do you see anything else that may be an issue?

Numeric Value 102 is NOT a consecutive duplicate as described in my original
post. However, the Formula does incorrectly return Numeric Value 102. I think
this could be part of the problem and solution.
