Does anyone know if there's an easy way to automatically add a value from one table column to another table column each time a record is added to the second table? I know it can be done with a hidden input tag in the HTML, but is there another way to accomplish the same thing by using a global or editing the add_record sub in Home.pm?

I'm concerned about the security of the transfer of this value, so I don't want to use hidden inputs because users could edit them in the browser's URL field. Any ideas?
