whatever your problem, it's probably being caused by incorrect use of double quotes here:

<?php echo " Product:<br/> {$_POST["product"]}";?><br/><br/>

change that to:

<?php echo " Product:<br/> {$_POST['product']}";?><br/><br/>

(single quotes around product).

Honestly no idea what is causing the problem. Tested it with your code at my pc and it worked like a charm. (PHP 5.2.6)

 

Something similar happened once to my friend and he had to restart apache and it fixed it self.

 

One of the reasons why it would show you the code instead of result would be that its not php file but html file instead.
