Populating Hidden Field Value with Value Entered in CMS

Go to End

I have created a custom field called retURL for the user to enter a URL in the CMS. I want to access this value in the Custom form hidden field.

I have tried the following and get the value "Array" back:
new HiddenField("retURL","retURL",DataObject::get('RegistrationForm')->column('retURL')),

Can someone point me in the right direction on how to access the retURL value for the specific page that is created off of this RegistrationForm page type?

class RegistrationForm extends Page {

static $db = array(
'retURL' => 'Varchar(255)'

function getCMSFields() {
$fields = parent::getCMSFields();
$fields->addFieldToTab('Root.Content.Main', new TextField('retURL','Page URL'), 'Content');
return $fields;

} //class RegistrationForm

class extForm extends Form {
function init() {

class RegistrationForm_Controller extends Page_Controller {

function Form() {
return new extForm($this, "Form", new FieldSet(

// List your fields here
new TextField("first_name", "First Name"),
new TextField("last_name","Last Name"),
new HiddenField("retURL","retURL",DataObject::get('RegistrationForm')->column('retURL')),

), new FieldSet(

// List the action buttons here
new FormAction("", "Sign up")

), new RequiredFields(

// List the required fields here: "Email", "FirstName"
