It's not designed to be implemented. It's just a code sample - you'll need to learn a bit of PHP before you can do it. Basically you can't do what you want without knowing one type of scripting language or another...

You could use javascript conditionals, or verify the users input in the script that processes the form.

For instance in PHP you could do something like:

<?php
if($_POST[radiobutton] == \"blah\") {

    if(!$_POST[input1]) { $error .= \"you have not entered input 1<br />\";
    if(!$_POST[input2]) { $error .= \"you have not entered input 2<br />\";

}

if($error) {

    echo(\"<p>$error</p>\");

} else {

    //**** process form

}
?>
