What is my best option/method to hide rows with duplicate data?

I only care about checking for duplicate data in one column.

I think I have a very simple solution.

I have a main loop that goes through every row and within the main
loop I have a second loop that looks at each row below the current row
and if the data in the criteria cell is the same then I just hide the
row.

It seems ot work but it will take some close review to make sure it's
doing what I want it to.
