Hi folks! I'm hoping someone can help me with an error I'm getting which is preventing me from amending existing catalogue records or creating new catalogue records. Whenever I try to save a record, I receive the following error: Tag "" is not a valid tag. at /usr/share/koha/lib/C4/Biblio.pm line 575 Checking through the community's documentation in manuals, wiki and IRC logs, I think I have tracked it down to the following lines: 575 my $authfield = 576 MARC::Field->new( $authtypedata->{auth_tag_to_report}, 577 '', '', "a" => "" . $field->subfield('a') ); However, I don't know where I go from here to fix it. We're using Koha version 3.12.03.000. Many thanks. Catherine PS we did finally get our self-loan station up and running, after much toing and froing with the vendors.
