This is a classic problem. You need to have an index which you can regenerate from the database (e.g. record id or employee number or something like that.)
When you generating names of the text boxes you have to generate them in a way, so that you can generate the same sequence everytime. Only then you can match the submitted text with the original text. Other idea could be to send the orignial name (first name + last name) as hidden variables in the form.
