Hello all,

We recently installed Koha for our small library, and we don't have any exposure to library sciences, we're just amateurs. We could install Koha properly. But there is one error which is showing up at the end of adding the item. I couldn't attach the csv file of our customized MARC structure for the 40KB limit of mails.

screenshot of the error:

Software error:

Can't call method "subfield" on an undefined value at /usr/share/koha/lib/C4/Biblio.pm line 2881.

For help, please send mail to the webmaster (webmaster@debmaker32), giving this error message and the time and date of the error.

Even if we use the default MARC structure, we still get the error. Interestingly, the item gets added to the record. However, while checking out the item against a patron, after giving the Barcode and pressing ok, we hit the same error page again. Even while returning the book once we click on return the book, the same error comes. We saw some community pages where people encountered this kind of a problem. We don't have any clue to fix this. Any inputs? Thanks in advance.
