So, I am suspecting that the columnheadings were improperly read.

There's an easy way to check that. After reading the column headings, insert this code: 

use Data::Dumper;
print Dumper \@columnheadings;

Run your script, and see if the output matches your expectations.

  • 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.
  • Please read these before you post! —
