I am seeking a way to identify duplicate Invoice numbers in a column
Say Col a
123453
123654
321010
362511.
if
123453 is entered then I am seeking some visual alert indicating a duplicate Invoice No.
Like also to use this for Names in Col c [Surname] and d [First name]
Is there a way tp achieve this please
Help Appreciated
