Add auto filter (unique records) option to macro

Hello, I have been modifying a workbook and the original macro will send to the sheet Results once the "Search" button is clicked, but I have found that this macro is displaying duplicate records. Can anyone help me put in an auto filter to find only unique records? My second workaround option is if someone can help me remove the go to/select sheet option from the "Search" macro so that a user will not automatically be sent to the Results tab and will instead hit the "Confirm Category Selection" button (which auto filters before sending the user to the Results tab). I would be forever indebted to any help people can provide, I am very very new to VBA and appreciate all the help I can get!
