Radio Buttons Limited to Named Users
I am currently designing a database to keep track of order and invoice approvals. My intention is to design a system where each manager (sales, legal, accounting, etc.), can log in and approve each order themselves. However, I would like to limit the ability of each user to only click on their respective radio button, and not be able to edit other people's approval field.
Is there any way of telling Filemaker to limit each user to his/her respective approval radio button?
