Attributes and Stock Control

Still configuring my site and learning about Zen Cart!

I have worked out how to set up and apply product attributes like size, colour etc.
What I can't yet do is link it to stock levels to prevent the ordering of out of stock items.

For example, if I have an item in 3 colours, I may have 5 red, 10 blue and 3 green. This is a total of 18 items.
But if I sell all 3 green, how do I stop a customer ordering another green, because I still have a total of 15 left!

basically I can't see how to set a stock level for each attribute.

Thanks in advance for your help

I'm not familiar with this add on, but it's worth a look http://www.zen-cart.com/index.php?main_page=product_contrib_info&products_id=326

I would actually recommend using PRODUCTS WITH ATTRIBUTE STOCK. It's a much better mod. I tried both.

I have even modified further to include SKU numbers and include them in the orders for my knowledge. Since we deal with many products and many shipments, I need to keep track of what products and what shipments are coming from my manufacturer, so I modded Stock by Attribute to give a different internal SKU for each product and variant. If you have any questions about how to do it, let me know.
