Filter custom post type loop if check box is true

Hi Im trying to create a featured posts section, using the “Custom Filed Suite” plug in

I want to show a post/posts from 2 custom post types, but only if the check box is checked.

the loop i have so far is

<?php
// query the posts of your custom post types

query_posts( array(
'post_type' => array(
'post',
'bha_news',
'bha_members_news'

),

'showposts' => '10' ) // or 10 etc. however many you want
);

?>
<?php
// have some posts?
if (have_posts()) :
while (have_posts()) : the_post(); // begin the Loop ?>

<?php the_title(); ?>
<?php
endwhile;
endif; wp_reset_query();
?>

The code to retrieve the “custom field suite” meta value is

<?php echo $cfs->get('field_name'); ?>
but i have no idea where or how to filter using custom field suite….

I only want to show posts where the custom post type matches and where the checkbox is checked.

I hope this makes sense?
Many THanks for any help?
