Hello, thanks to Joshua Ferraro and Ryan Higgins for helping me understand this problem more. See the thread "inventory.pl not working for me" for the history of this discussion. My problem is that our librarian cannot currently do inventory because we have not been entering in a value for items.itemcallnumber (which I believe to be MARC 082b). Our call number is, however, recorded in the database field biblioitems.classification. What seems to be the solution is for the value of biblioitems.classification to be copied to, or synced with, the value of items.itemcallnumber. I'm sure that if I knew SQL decently that I could invoke some command to do just that. I don't know SQL. Could anyone give me a way to copy biblioitems.classification to items.itemcallnumber? I'm assuming that this syncing of fields would solve my problem and that then our librarian could begin working on inventory. Thanks in advance to any help you can give me in this area. -Matthew
