Is it not?You're adding numbers to something that doesn't already have unique identifiers in it? The tough part there is going to be figuring out how to uniquely determine which record you want to modify. For instance, the [Replace] context which you'll be using for your renumbering task needs to be given a set of search criteria that uniquely identify the record. If you give it something non-unique to search for, then it will end up renumbering all found records with the *same* number.So your task is to come up with a search that will always find just one record. Once you can do that, you can use a little [math] to increment a number once for each found record, then [replace] the sku with that number.Technical Support | ==== eCommerce and Beyond ==== Pacific Coast Software | WebCatalog, WebMerchant, 11770 Bernardo Plaza Court | SiteEdit Pro, PhotoMaster, San Diego, CA 92128 | Typhoon 619/675-1106 Fax: 619/675-0372 | http://www.smithmicro.com/ Associated Messages, from the most recent to the oldest:
