Simulating the Back button

Hi,
I have an html form with several text boxes. When the form is submitted it calls as ASP routine that updates a database based on the inputs. Before the actual update occurs a textbox is displayed showing the data being submitted with a "Is this correct?" prompt.
What I'm trying to do is if "No" is selected the html form reappears with the data still in the text fields so it can be edited then resubmitted.
If I click the Back button on the menu this happens.
I thought I could use <a href=TheForm.html>No</a> but this created a new blank html form.
Thanks,
Al.
