[Koha] Koha error

[pandu rangaswamy]

Dear All,

I tried to import the data(Books) from the existing koha 3.0 version to
Koha version 3.10 in ubuntu 12.4. When i searched it shows only Books
Biblios data only, its not showing the item details. Then i did undo the
imported data, after that if i search again it shows 116 books. if i tried
to edit record it shows the following error.

Software error:

Can't call method "title" on an undefined value at
/usr/share/koha/intranet/cgi-bin/cataloguing/addbiblio.pl line 815.

 For help, please send mail to the webmaster ([no address given]), giving
this error message and the time and date of the error.


Kindly guide me to slow the error.
