Hi, I need some help on error msgs that I am getting while trying to catalog. using 3.2 on ubuntu. all cataloging was fine until I got these msgs. i have cataloged 2600 titles all downloaded from LOC and now these msgs. 1. All arguments must be MARC: field objects at /usr/share/koha/intranet/cgi-bin/cataloguing/addbiblio.pl line 149 and 2. Can't call method "subfield" on an undefined value at /usr/share/koha/intranet/cgi-bin/cataloguing/additon.pl line 79 what do these pl lines represent? what MARC field do they represent or do they?? help!! thanks in advance!! margaret at Valentine isd, Texas
