    Your PHP script is likely causing a server error due to improper coding. Check your server logs for PHP related errors, and possibly turn on error_reporting for PHP.

    Within your PHP script, you have a statement of:

    if ($POST[ 'dir'] == "1") <?php echo "$_POST["cvalue"]; ?> feet = <?php echo "fTOm"; ?> meters;

    Since you’re already in a PHP script, why are you using the <?php echo inline an if statement?? Correct this issue and try running the script by directly calling it.

    Change the if line to :

    if ($POST[ 'dir'] == "1") {
  echo $_POST["cvalue"] . "feet , " .  $fTOm . " meters";

}
