    Hi,
    I think you want to use the Map operator and not Replace? Replace is to be used with regular expressions.

    Hi,
    okay, so you want to use regular expressions to replace parts of strings?

    Replace your numbers as follows : \b1\b, so 12 becomes \b12\b

    This way the system knows it needs to replace the full number (12), and not 1 and 2 as that would be the default otherwise.
