Step validation: review is not a valid step.

[barrychapman]

Whenever I submit on my 'location' step, i use $this->Wizard->branch( 'us' ) to switch to the US branch below, but I get the following error:

Step validation: review is not a valid step. [APP/plugins/wizard/controllers/components/wizard.php, line 300]

        $this->Wizard->steps = array( 
            'location',
            array(
                'us' => array( 
                    'dwollainfo'
                    ),
                'nonus' => array( 
                    'numbers',
                    'accounttype',
                    array(
                        'personal' => array(
                            'personalinfo'
                            ),
                        'business' => array(
                            'businessinfo'
                            )
                        ),

                    )
                ),
            'review'
            );

It SHOULD be taking me to the Us -> Dwollainfo step right? Why is it throwing an error that review is not a valid step?
