Hi All,

When adding Items to Bibliographic Records in Koha v3, I am receiving the following error message:

Software error:

Can't call method "subfield" on an undefined value at /home/koha/kohaclone/C4/Biblio.pm line 2880.
For help, please send mail to the webmaster (webmaster@koha), giving this error message and the time and date of the error.

Can someone please help me with this error?

Kindest Regards,
Joel
