i had never done this but my idea is to show all entered data before submit.
otherwise you should wait for submit and in yourForm->trasmit->after Transmit you can access the submitted data, redirect to another form and fill it with the submitted data...may this is going to be a way..
another way is to redirect to a new form and give the Id of the entered data as a parameter..then load from database and fill in the values..
