Hi Scott But the key has to be nice (= unique)! /gustav >>> marcus at tsstech.com 23-01-2005 05:33:41 >>> Steve, The key doesn't have to be sequential, doesn't have to be the primary key, and doesn't have to be numeric. It just needs to be a single field key (one could probably get around that restriction also with concatenation).
