List-based inventory help

Basically, I'm trying to create a list-based inventory. Currently, I'm using a list object with a hash table, and my current problems are:

1. Getting everything on the list. For some reason, the last item is repeated and with no value.

2. Double-click actions based on the item double-clicked. I haven't managed to figure out how to grab the specific item on the list and compare with the hash table.

Here's the .cap.

looks like a bug in hash why is "falcon" not being added? maybe that's the duplicate entry somehow?

Smeg if I know. Still, my real problem is modifying the hash table through the list, for example, double-clicking on a specific item would make the item in the table reduce by 1, but... HOW to do that, is another thing entirely.

I don't think the 'clicked' or 'double clicked' event even work...

Seriously? That's strange.
