Querying by post type using magic fields plugin

I need to set another loop on a page, I’m using magic fields plugin, where “news” is the name of the Custom Write Panel.
for some reason its not displaying the posts.

<?php $my_query = new WP_Query(‘post_type=news’);

while ($my_query->have_posts()) : $my_query->the_post();

$do_not_duplicate = $post->ID; ?>

<?php the_title(); ?>
<?php the_content(); ?>

<?php endwhile; ?>
