Well hopefully the error can easily be seen if it's a duplicate entry in
a table or something along those lines, and your IE will prompt you
before reposting form data. However, you can set a session variable that
identifies that the "process" you are performing has already been
completed. So after the insert is complete it will set the session
variable as 1, then if they press repost the variable exists and the
data will not be inserted again, and when the user clicks on the correct
menu to prompt to insert "new" data into the database, the variable will
be unset, so the insert can pass through, and then set again to stop
futher duplicate posts of the same data. Hope this helps.
