The reason being - your page may be called from pages other than the 
form (i.e., someone typing the URL into the browser bar), in which case 
$_POST['price'] and $_POST['number'] won't be set.  This code will set 
0's into $p and $n should the values not be set.

Better yet - don't put things like prices in hidden fields.  It would be 
very easy for me to create a form on my own machine which sets a price 
of 1.  You can display the price to the user, but keep critical values 
like this on the server.

Remember - NOTHING from the user is ever safe and EVERYTHING needs to be 
validated.
