How to change the text of the "checkout" button in Drupal commerce cart? How can I change the text of the "checkout" button in Drupal commerce cart?

I need it to be "continue" instead.

thanks



   function rooms_form_alter(&amp;$form, &amp;$form_state, $form_id) {  
      dsm($form_id);  // print form ID to messages
      switch ($form_id){
            case 'views_form_commerce_cart_form_default':
                $action['#value'] = 'continue';
            break;
      }
    }
By using the hook_form_alter() function, you can change the text of the buttons. It would be something like 

$action['#value'] = 'continue';


Please provide us with more code so I can work out a decent example.
