what's in any cell from a cannot be in b
a client of mine works for prada, he cut the leather into shoes
he receive barcodes wich are a certain pair of shoes to cut
when he cut them he send them back to prada
but he never know what he have in his factory, or what he sent back to prada from these barcodes
he need somethig simple, so when prada ask him for a barcode, he can check the excel what colums contain that barcode
when he receive the barcode, he write it into the column A
when he send back to prada the barcode, he write in the column B
but the column A have to delete the barcode he wrote in B to avoid duplicates
