all is working in the checkout proccess untill the final stage.
when sending the info and presenting the order i get this error message:
: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in C:\wamp\www\or_02\checkout3.php
on line 168
: extract() [function.extract
]: First argument should be an array in C:\wamp\www\or_02\checkout3.php
on line 169
even though i checked and re checked i write the same code as the book.
