So even if SM could guarantee that the cart tag would not create a duplicate value on its own, they cannot control your computer clock.If you're that concerned about getting an absolutely unique value every time, why don't you use a database to store the last number used as a unique value, and increment it by one each time someone new visits the site? You won't be able to use the [cart] tag if you do this, so you won't have to be concerned about whether or not the [cart] tag is going to give you what you want, because you'll be dealing with that yourself ... :) ================================ Kenneth Grome, WebDNA Consultant 808-737-6499 http://webdna.net ================================------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
