Drupal7 Custom Form Submit Handler Not Working - forms

Question

I am writing a custom module which has a form but the submit handler is just not working, the form just submits back to itself?
Any help much appreciated.
I have an add guest custom form and that is working fine.
The URL on my site is: /user/booking_editguest/LBD0413/1
The code is below:
function uUserBookings_editGuestForm($form, &$form_state, $ManageBooking) {
//var_dump($ManageBooking);
$guestSeq = arg(3);
$masterEventCode = $ManageBooking->Contact->{'MasterEventCode'};
$eventCode = $ManageBooking->Contact->{'EventCode'};
$attendeeContact = $ManageBooking->Contact->{'AttendeeContact'};
global $user;
$account = user_load($user->uid);
$memberCode = $account->name;
// booking
$form['booking'] = array(
//'#type' => 'vertical_tabs',
);
foreach($ManageBooking->guests as $Guest)
{
if ($guestSeq == $Guest->{'GuestSeq'} )
{
$form['guest_form']['FirstName'] = array(
'#required' => TRUE,
'#type' => 'textfield',
'#title' => t('GUEST FIRST NAME'),
'#default_value' => $Guest->{'Guest FirstName'}
);

);
//ID uniqueidentifier

);
}
}
return $form;}
function userBookings_editGuestForm_validate($form, &$form_state) {
// Validation logic.
// Don't custom-validate if previous validation errors (still) exist
if (form_get_errors()) return;

$id = $form_state['input']['ID'];
//Redirect back to the Booking.
$form_state['redirect'] = '/user/booking_guestupdated';}

For those using hidden textfields and have them set as required, make sure you check the values being entered!
