ActionScript for radio buttons?

Hey,

I have set up a simple email form in flash that sends input from my text input fields to a PHP file that sends it to my inbox. This works fine, but I would also like to add three radio buttons to the form. How can I do that?

I have tired to add three radio buttons in my ‘form’ movie clip and have set the parameters, but I think I need some ActionScript to make the radio buttons send their info along with the text input. This is my ‘send’ button:

on (release) {
form.loadVariables(“email.php”, “POST”);
}

So I guess what I need is to get variables from the radio buttons to be sent along with the text. Can anyone help?

Thanks in advance, Sverre
