Check box automatic populating issue

Check box automatic populating issue

Hello

I have a check box in the first and second view of my database.  With existing records if I uncheck the box in the first view it does not reflect in the second view.  

Please can you advise what deluge script I should use?  

I’ve used a “ input.Commercial = main.Commercial; ” script which works with new records, but if I uncheck the box in the new record in the first view it still does not reflect in the second view.  This is also the same with date fields.

Thank you very much.
