If I understand correctly what you are trying to do can't be done with "normal" hashes. Normally a hash can contain only one value for each unique key, and therefore you overwrite the value each time you assign a value to a particular key. So you have two obvious options (in other words that I can come up with right now), you can tack on a unique identifier to the key: 'Akorn Drive Part 1','Akorn Drive Part 2' for instance, which is ugly and tedious, or you can use a hash of arrays, where you store a reference to an anonymous array as the value of the hash key, and then push each of the values to the array contained therein. There may also be a module that does this sort of thing, but I am unaware of it off the top of my head.
