Hi all,
I've a Go back button when clicked it goes back to the previous form . The previous form has a text box which gets value from its previous form. I need to know when i click the back button how to show the text box values previously displayed. Instead it executes the validation to that form and
displays as below code.Plz help.

if($query1 == "")
{
?>
  <br><br><center><img src="\images\exclamation5.jpg" width="100" height="100">
<h3>You have not selected any Display Field!!!</h3></center>	
  <center><h3>Select at least one Display Field and try again.</h3></center>
  <br><center><input type="reset" value="Go Back" onclick="goback()"></center>
<?
  exit;
}

Try save the form's values to sesison vars then if the form is incomplete, when you go back echo the values back to those fields
