Description:
------------
? am reading the book ?PHP & MYSQL Web Development" 3d Edition,of Luke Welling & Laura Thomson.
The example of chapter One has the files orderform.html & processorder.php.
The form action of ordderform.html is:
form action="processorder.php" method="post">.

Reproduce code:
---------------
In the beggining of processorder.php file there is:
<?php
  // ?????????? ???????? ???????? ?????????? 
  $tireqty = $_POST['tireqty'];
  $oilqty = $_POST['oilqty'];
  $sparkqty = $_POST['sparkqty'];
  $find = $_POST['find'];
?>

An in the continue there is:
   echo $tireqty.' tires<br />';
   echo $oilqty.' bottles of oil<br />';
   echo $sparkqty.' spark plugs<br />';

Expected result:
----------------
As I load the processorder.php file in my browser, I expect that the script output should resemble the actual values, depend on what I typed into the orderform.html.

Actual result:
--------------
I see in my browser all, exept the actual values.
