This is because when the form is first submitted, nothing has been submitted, and thus $HTTP_POST_VARS['fname'] has no value. PHP is simply warning you that you're trying to use an unitialized value. Check the value first and you'll not have a problem with it: <?php $output_fname = isset($_POST['fname']) ? $_POST['fname'] : ''; ?> <input name ="fname" type="text" value="<?php echo $output_fname ?>" /> If the first line looks odd, check out: http://ca2.php.net/manual/en/language.expressions.php You could just turn down your error reporting, but all that does is hide from you the fact that you're using code with problems in it. You should make sure the code executes in a development environment with full error reporting on without warnings or notices, before you turn off error display on the production box.
