Ideas on creating an inventory?

Hi, I’m trying to create an inventory for a very basic flash site that I’m making, but I’m still learning how to use flash more creatively.

I have a couple of scenes that I have made in photoshop and I’m now trying to use flash to tie it all together. I’ll attach some pictures.

In the first picture is a frame layer with a selection of coloured mushrooms. I want to be able to pick them up and store them in an inventory.

In the second picture, I want to be able to move the mushrooms from the inventory into a cauldron in a predetermined order - e.g. blue, red, green, orange, yellow etc. In order to create a potion.

I’ve been told that it’s possible to make something like this using an array.

Any advice, tips, links, suggestions would be greatfully received…even just a gentle nudge in the right direction
