Putting [cart] in your template automatically creates a unique shopping cartPutting [cart] in your template automatically creates a unique shopping cart that can be used in eCommerce. You must continue to pass the [cart] value from page to page (or store it in a cookie for retrieval) in order to continue writing and modifying the shopping order (using tags such as [addlineitem] and [setheader]). If no cart value is specified when the customer lands on a new page with a [cart] tag, then a new unique value is created displaying an empty cart, and you will lose contact with the previously created cart. ([cart] will never display in its literal raw form, unless WebDNA processing is turned off altogether.)
