So I have two columns in Excel with these values suppose: Column A | Column B ---------|--------- 12 | 626 241 | 129 35 | 412 412 | 88 532 | 663 626 | 723 | 88 | 932 | What formula should I use to delete the values 88, 626 and 412 from Column A (applying the formula then going to Goto Goto Special Errors... and deleting rows) Can't quite get this sorted at all!
