showing unique digits only

Hello,
As per attached file could you please let me know know how can i show data for only listed items (Col B) to Unique Items (Col D)

Thanks

using CSE formula...confirmed by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. You will know the array is active when you see curly braces { } appear around your formula. If you do not CTRL+SHIFT+ENTER you will get an error or a clearly incorrect answer. Press F2 on that cell and try again.
