I have a form to record staff information , and HR staff need to edit some column of the form and submit the form to other department. I have a check box for the staff to record stationary they need in the form, which is a checkbox that can have multi-select. I would like to know that, how could I set the default value of the check box that following the choice of the previous record. When the HR edit the form , if the check box is checked , keep the check box checked, if not , keep it false.
