First of all, a little bit of terminology: the "object" you're referring to is called an associative array. Not "associated". They're also commonly called hashes because their implementation is based on the concept of a hashing function.

Said this, if what is happening what both I and everyone else thus far are guessing, i.e. that you failed to properly declare a certain hash as lexically scoped to your sub, then it is worth repeating the single most precious piece of advice we usually give to Perl newbies:

use strict;
use warnings;

To be sure, let me rephrase the above advice in these terms: "let perl do all that it can to help you avoid trivial mistakes".

Incidentally, use code tags just like quite anybody else for your pieces of code rather than ad-hoc visually disturbing (IMHO) formatting.
