    ?>
         
    <label>Number of coffee</label>'

It would be nice if you could post your entire code as I can’t see if you have placed all your form fields inside a form.

You access values from a form using super globals $_POST, $_GET or $_REQUEST (more or less a merge of the previous two).
Make sure you use $_ and not just $.

Also note that only fields with a name attribute will make it to PHP land and it’s that name attribute you should use when accessing variables. So double check the names you are trying to access: num_cream instead of numcream, size instead of Size, etc.
