Product inventory guestion

I have a client that will be selling clothes online. And the inventory is lite so I am looking for a module that will allow me to make the inventory by the size instead of the product. For example if I have a pink shirt and she will have 2 Smalls 1 med 3 large and 10 xlg. That's it in a nutshell I have found modules for everything else just not this one. Thanks for the help everyone was very helpful in the past and taught me a lot about zen cart.

Look into the download section, there is a module that does that. Quantity By Attribute I believe.

Perfect that is exactly what I needed. Thank you for the help.
