Display posts from custom post type

Hi there, im trying to display the very last post from my new custom post type called call to action. I have created this function which works great.

add_action( 'init', 'register_themepost4', 20 );

function register_themepost4() {

 $labels = array(

 'name' => _x( 'Call To Action', 'catchthemes_custom_post','catchthemes' ),

 'singular_name' => _x( 'calltoaction', 'catchthemes_custom_post', 'catchthemes' ),

 'add_new' => _x( 'Add New', 'catchthemes_custom_post', 'catchthemes' ),

 'add_new_item' => _x( 'Add New calltoaction', 'catchthemes_custom_post', 'catchthemes' ),

 'edit_item' => _x( 'Edit calltoaction', 'catchthemes_custom_post', 'catchthemes' ),

 'new_item' => _x( 'New calltoaction', 'catchthemes_custom_post', 'catchthemes' ),

 'view_item' => _x( 'View calltoaction', 'catchthemes_custom_post', 'catchthemes' ),

 'search_items' => _x( 'Search calltoaction', 'catchthemes_custom_post', 'catchthemes' ),

 'not_found' => _x( 'No calltoaction found', 'catchthemes_custom_post', 'catchthemes' ),

 'not_found_in_trash' => _x( 'No calltoaction found in Trash', 'catchthemes_custom_post', 'catchthemes' ),

 'parent_item_colon' => _x( 'Parent calltoaction:', 'catchthemes_custom_post', 'catchthemes' ),

 'menu_name' => _x( 'Call To Action', 'catchthemes_custom_post', 'catchthemes' ),

 ); 

 $args = array(

 'labels' => $labels,

 'hierarchical' => false,

 'description' => 'Call To Action',

 'supports' => array( 'title', 'editor', 'excerpt', 'thumbnail', 'revisions'),

 'show_ui' => true,

 'show_in_menu' => true,

 'menu_position' => 5,

 'show_in_nav_menus' => true,

 'publicly_queryable' => true,

 'exclude_from_search' => true,

 'query_var' => true,

 'can_export' => true,

 'public' => true,

 'has_archive' => 'calltoaction',

 'capability_type' => 'post'

 );

 register_post_type( 'calltoaction', $args );//max 20 charachter cannot contain capital letters and spaces

}

But i now have difficulties displaying the actual posts from this new custom post type.

I created this loop here:

<?php
	 // The Query
	 wp_reset_query();
	query_posts('post_type' => 'calltoaction'); if (have_posts()) : ?>  

    <?php while (have_posts()) : the_post();?>  

		<?php the_permalink(); ?>

            <h3><?php echo substr(get_the_title(),0,58); ?></h3>

            <?php echo  get_excerpt(190); ?>

    <?php endwhile; ?>  

<?php else : ?>  

	Sorry, no call to action posts were found.
<?php endif; ?> 

<?php wp_reset_query(); ?>

Clearly it must be the ‘post_type’ => ‘calltoaction’ line, but im not sure what else i could try as im not too hot with the syntax.

Any help would be really appreciated.

Thank you
