Need help with matching # of items added to shopp crt to # of items have in inventory
I have completed the shopping cart up to the point to where the user selects the item, it adds it to the shopping cart, updates, etc. Then the direct to shipping and billing information and to Shopping cart review and customer information. It all works fine but for one item. When I select an item for the shopping cart, (I have only ONE of the item). I select it to add to cart, I continue shopping, click on the same item and it adds a second one to the cart. I only have one. How can I correct this so it will not do so. Also, if another buyer is looking at the same item, is there a hold on the item until the first customer decides to buy or not?
