Forms designed off of a database allow you to submit right back to that same database.
If you want to modify your form's schema (for example, by adding a new field) that data cannot be submitted to that same database.
You'll need to write a web service that submits to the database.
Previous discussions all point to similar solutions:
(a) You create a db-bound
form.
(b) You write your own web service.
(c) You use
a tool like DBXL to map the data. Unfortunately, this is for SQL only, not Access.
This is a great post
which covers b and c. Good luck!
