I agree that it resolves the Back button problem, but it creates a new 'Reload' button problem:When the user click the Reload button on the [append] page you described above, a new duplicate record is appended - with exactly the same data as the previous record.What makes this even worse is that the user can simply continue to click the Reload button - hundreds or thousands of times - and each time that button is clicked, another identical duplicate record is appended to the database!Sincerely, Ken Grome ..... ken@iav.com http://usarea.net/home.html
