Hello Everybody, A pleasant good day to you. My name is Imran Mohamed from the University of Guyana and I am a part of the team that is currently customizing Koha ILS v3. We are almost through setting up the relevant frameworks and customizing the software. However, we are experiencing some problems in one of the framework. The error is encountered when adding a MARC record and is as follows: Koha error The following fatal error has occurred: Tag "" is not a valid tag. at /usr/share/koha/lib/C4/Biblio.pm line 2534 Apache Server version: Apache/2.2.9 (Debian) Server built: Jan 20 2009 17:29:25 Koha 3.00.00.107 Koha DB 3.0000107 MySQL mysql Ver 14.12 Distrib 5.0.32, for pc-linux-gnu (i486) using readline 5.2 OS Linux canaan 2.6.18-6-k7 #1 SMP Tue Jun 17 22:06:22 UTC 2008 i686 GNU/Linux Perl 5.008008 Another problem we are encountering is when a book is overdue, the fines are not calculated although the book is showing up as overdue. All of the fine rules were already set up. Also, seeing that we are almost finished customizing, we would like to know what is the best way to enter records into the system. Would it be best manually, one by one or use the Library of Congress database. Please advise us as soon as possible. Thank you.
