Can anyone point me to a solution for this?If you are worried about people backing up this far and reordering, you can just use some [showif] checks to present them with a message that this cart has already been submitted, and give them a $newcart link instead of allowing them to shop with that cart again. You could either use [showif] in conjunction with [listfiles] to check for the existence of that cart in the Orders folder, or, more conveniently (since you already have the orders database set up) you can do a [lookup] in your orders database to see if that cart number has already been ordered.Alternatively, you could make all links between pages form buttons using METHOD=POST; this wouldn't prevent them from backing up and using the same cart, but it would make it more difficult.I hope this helps,Marc Eagle StarNine Technologies http://www.smithmicro.com/
