I want to populate Subform field with multiple rows from Main form field update.

Main form is Customers. The field for updating is Customer_Company.

I have add Field Actions in Subform On Add Row to populate the same field in Subform. So every time add new row in Subform automatically copy the value of Customer_Company to same field in Subform.

What I want to ask is, when I update the Company field in Main form, I want all the field in every row in Subform also changed.

Please help. Thank you.
