Google-sheets – Conditional Formatting in Google Spreadsheet

conditional formattinggoogle sheets

I have a list of addresses in column C for work orders, I'd like them to be highlighted if there are duplicates so we don't forget a work order on each visit. These work orders/results are dynamic and the list will change daily.
