Need help with an inventory system

Hello, I want to make a program that can load and unload some movie clips with buttons. Basically, i have ten different items, and ten inventory slots. I want to be able to load the items into the inventory slots in random combinations and be able to unload them aswell. Each item has its own add and remove button. I looked through the search and tutorials but they show just mostly inventory done with hit test, for games and such. I just need someone to give me a basic idea for the best way to do this. Any help would be highly appreciated, thanks.
