It is probably best to put the individual items in a separate table and link their keys, as an example with 3 tables table items itemid name table item_list pcid itemid table pc pcid location then these could contain items itemid name 1 memory module 2 floppy drive pc pcid location 1reception item_list pcid itemid 11 11 12 so reception pc contains 2 memory modules and 1 floppy Hope that helps -- regards, Tom -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
