I get a:
Warning: Invalid argument supplied for foreach() in c:\apache\htdocs\or_6.4.php on line 15
after submitting the form.
Hello Anthony!
As long as you don't submit the form with a single option selected there will be no $_POST['lunch'], therefore foreach() won't be able to loop through it.
Add the line print_r($_POST) to your code in order to see what actually happens if you hit the submit-button of your form.
