This is another instance of not using the tool to it's full potential. I have never seen a single instance of someone wanting to store multiple values in a single field that wasn't more efficiently done using multiple rows in a database instead.Create a new database favorites.db with the following columns:userid
hitsSKUwhere [userid] is whatever you have as the unique identifier for the user in your visitors.db.However you want to add the items to the favorites.db initiall, set the [hits] field to 1. As they chose that same link more than once, increment the [hits] column each time. You may want to ensure that they don't have more than X number of favorites (I would suggest 10 or so as the max); you will need to create logic to replace the last record with the new item if they already have the maximum number of favorites listed.Then, when you want to display their favorites list, do a search with reverse sorting on the [hits] column and within the [founditems] loop, do a [lookup] or [search] of the products database for that item's info. This scheme will autosort their favorites in decreasing order of how favored the items it.QEDJohn-- John Peacock Director of Information Research and Technology Rowman & Littlefield Publishing Group 4501 Forbes Boulevard Suite H Lanham, MD 20706 301-459-3366 x.5010 fax 301-429-5748 ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list .
