If I understand you correctly, you just need to change this line: 

    if (exists $hash{$nam[0]})

[download]
to this: 
    if ( grep { exists $hash{$_} } @nam )

[download]

If not, then trim both your input files to the bare minimum of data needed to demonstrate the failing behavior, and post them in this thread.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
