Help needed with multi step form

Hi All,

I'm having trouble with a multi step form. The form is basically a questionaire with radio buttons (radios) to select the answers (max 3 choices). When the submit button is clicked on the first page, the radio buttons all seem to stay at their default value. I'm using krumo with the Devel module to inspect the variables. Code below...forgive the messy code...still in development!

<?php
/**
* Valid permissions for this module
* @return array An array of valid permissions for the festivalmanager module
*/
function festivalmanager_perm() {
return array('access festivalmanager content');
}

//Admin page for Festival Manager module

function festivalmanager_menu() {
$items = array();
$items['festivalmanager'] = array(
'title' => 'Virtual Assistant',
'page callback' => 'festivalmanager_page',
'access arguments' => array('access festivalmanager content'),
'type' => MENU_CALLBACK
);

return $items;
}
function festivalmanager_page() {
return drupal_get_form('festivalmanager_myform');
}
function festivalmanager_myform(&$form_state) {

if (empty($form_state['storage']['step'])) {
// we are coming in without a step, so default to step 1
$form_state['storage']['step'] = 1;
}
switch ($form_state['storage']['step']) {
