Sorry for the long title...

I have an add me to your newsletter radio button. The next few fields are for address information. If they check the add me radio button I want the next few fields required.

How do I do that?

Thanks!!!!

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

}
?>

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...
