This is my Joomla Payroll System once again. To add you will need to set up the field in the Community Builder Component first. And you will also need then to find out what field in mysql that has created. I will write more on this when I need to add a field from scratch myself.
Here's the details on how to delete.
the table row for Resume entry
and REMOVED on line 884
$edit_resume=JRequest::getVar('edit_resume', '', 'POST');
FROM query1 on line 890
