Hi Izwan,

I suspect the issue is that the parent subject with the ID 'journal' does not exist.  Click on the Admin link in your menu and in then "Config. Tools" tab on the Admin page click on the "Edit subject" button.  You will need to create a 'journal' subject.  You can do this by adding the word 'journal' in the input box next to "Subject ID String" and then clicking on the "Create" button.  You will then need assign a label for this subject (e.g. Journals) and set whether it should be depositable (probably not, as this is a parent subject).  You will then need to add subjects under this parent 'journal' subject for all the journals you want a user to be able to choose from for this 'journal_in_university' field.  I would try to use a consistent format for these journal subject IDs like jrnl_nature for the Nature journal.

Regards

Dear all, I added a new field from Manage Metadata Fields - Eprints page. with type subjects. After i added the field in workflow, the system show Internal Server Error with error log 

[Thu Sep 09 15:22:46.543546 2021] [:error] [pid 109882:tid 139759477307136] Can't use an undefined value as an ARRAY reference at /usr/share/eprints/perl_lib/EPrints/MetaField/Subject.pm line 128.\n

The zz_webcfg_eprint_fields.pl setting is

  'export_as_xml' => '0',
  'input_boxes' => 3,
  'input_cols' => 60,

  'provenance' => 'user',
  'required' => '1',
  'sql_index' => '1',
