In drupal 7, I'd like to be able to change the page template if a value is returned in a CKK field. 

I tried: 

function themename_preprocess_page(&$variables) {
      $node =  $variables['node'];
      if($node->type == 'page') {
           if (isset($node->field_change_theme['und']['0']['value'])) {
                   $variables['theme_hook_suggestions'][] =  'page__newtheme.tpl.php';
          }
     }
}

A value is being returned but the theme is not changed.   Please help.

Thanks,
Tracey
