I just received an order where a customer ordered 4 items in large quantities. I can back order some of the items, since I don't have the quantity he ordered, but one item ordered is no longer being produced and I only had 1 in stock while he ordered 5. He also ordered 30 of an item when I only have 3!

Many of the items I sell are one of a kind art and cannot be sold in multiples.

Is there a way to keep the Zen Cart from allowing customers to order more than the total number of pieces in stock of products?

TIA for your help.
