I can't think of another reason why you would want to force a specific random order. And you do understand that [lastrandom] is only the last [random] from that page, don't you? If you move this between more than one page, you must either pass the [lastrandom] as a form var or use [SearchString].HTHJohn-- John Peacock Director of Information Research and Technology Rowman & Littlefield Publishing Group 4720 Boston Way Lanham, MD 20706 301-459-3366 x.5010 fax 301-429-5747------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
