Undefined Index Errors Galore

[jjfletch]

I've got a form that displays correctly, etc., yet when it comes time to submit, I receive the following errors:

An error occurred in script /home/virtual/site4/fst/var/www/files/config.inc on line 7: Undefined index: did

An error occurred in script /home/virtual/site4/fst/var/www/files/config.inc on line 7: Undefined index: dname

An error occurred in script /home/virtual/site4/fst/var/www/files/config.inc on line 7: Undefined index: qset1

An error occurred in script /home/virtual/site4/fst/var/www/files/config.inc on line 7: Use of undefined constant HTTP_X_FORWARDED_FOR - assumed 'HTTP_X_FORWARDED_FOR'

Additionally, in the script, I ask that if the comments area is blank, to display the error message, "You have not entered any comments". This is another message I'm receiving, despite the fact that comments were entered.

Below, I'm posting three parts of the code. The first is my config.inc script, the second is the code from the form, and the last part is the form itself. Help is ENORMOUSLY appreciated.

Thanks....

CONFIG.INC

<?php

error_reporting (E_ALL);

function my_error_handler ($e_number, $e_message) {
  $message = 'An error occurred in script ' . __FILE__ . ' 
  on line ' . __LINE__ . ": $e_message";
  //error_log ($message, 1, '[e-mail]');
  // Production (send email)
  echo '<font color="red" size="+1">', $message, '</font>';
  }

set_error_handler('my_error_handler');
?>
