Hi,
first step in debugging...learn to love the var_dump() function :)
just add the following code to the do_calculate.php function
... <?php var_dump ($_POST); echo "<br>"; // set up the pricing assignments ...
This will display what is held in your $_POST variable. When you run the script at the start of your output will be the following
array(2) { ["beans"]=> string(16) "Ethiopian Harrar" ["quantity"]=> string(1) "3" }
Notice that beans and quantity are in double quotes.
From now it should be east to fix ;)

Wizards,
I am VERY new to PHP, paging through Meloni's 'PHP Essentials' I get the following error which I assume is very simple to solve, but for me. I have tried different approaches in identifying the 'price' variable with no luck:
error:
Notice: Undefined variable: price in c:\inetpub\wwwroot\php exercises\do_calculate.php on line 20
Notice: Undefined variable: price in c:\inetpub\wwwroot\php exercises\do_calculate.php on line 24
