the biding code for the insert page is generated by the Validated Entries bindings. This will only be available if you use Server Validation to validate the page.
If you add Server Validation to validate the form on the insert page, a new binding group will be added to the bindings panel named Validated Entries, it is used to retain information in the form when validation fails.
the binding code on the update page is a modified version of the validated entries code.
on the update page, the server validation behavior is set to send a URL variable named invalid.
On initial load, the values from the WADAusers recordset are used to populate the form fields. If the form is submitted, and fails validation it uses the validated entries binding.
this is not code that will be generated by the bindings panel, it has to created manually
