Thus, you can replace all that code you use now with [cart].I prefer using [cart][date %Y%m%D%H%M%S] to generate the SKU value just in case I forget to dispose of the [cart] variable after adding a record or ship my code to another server which could conceivably cough up a [cart] that already existed on the previous server. Having a 24-digit SKU might seem like overkill, but it definitely avoids the bad juju from having a duplicate SKU. -- Andrew Vernon avernon@dramatols.net------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list .
