I have the following HTML form code:
   <form action="addvisitor.php" method="post">

When I submit my form, the PHP runs and updates my database, but I end up with a white screen with the echo text indicating the db was updated, but never end up back at my form.  The PHP file does not have a function, just the following (simplified):
  <?php
  $firstname = mysql_real_escape_string($_POST['first']);
  $lastname = mysql_real_escape_string($_POST['last']);
 
  $connected = mysql_connect(...);
  $select = mysql_select_db(...);
  echo(" Inserting " . $firstname . " " . $lastname . ".");
  mysql_query("INSERT INTO visitor (first_name, last_name)
              VALUES ('".$firstname."', '".$lastname."')
  ?>

I end up using the back arrow on the browser.  I'd like to go back to an empty form.  Any ideas?

Thank you!  That SOLVED it.
