As far as I can tell, you've added a third column.
Please click on the blue line at the bottom of this post and read the instructions on how to post example data in this forum. You will be using the pre tags to align your data. Please make sure that you repost your example data using the following criteria:
1 - Post a brief example of your input data, enough to show duplicates, anomalies, etc.
2 - Post the desired output based on the example input.
(Basically a "before and after" example)
3 - Make sure you include column letters and row numbers in both examples.
If you'll refer to Response #1 of the thread that you linked to, you will see an example of how your data should look once you apply the pre tags.
