I have attached a document to make this request a little easier as well.
I am trying to match data in sheet1 to sheet3. The matching data in sheet1 is in column I and it would look to match column F in Sheet3. Any match not found would be deleted (the row and data) from sheet1. There is a macro in there already, but it was created to find duplicates and delete the duplicates. Now I am trying to do the opposite.
Any help would be greatly appreciated.
