Want to add a random post type 'post' on homepage

Hey everyone,

I am looking to add a testimonial, which is a post type that i have successfully registered, onto the homepage. I would also like to show a random testimonial IE orderby=rand

Anyone have any ideas how to accomplish this?

Ive tried making my own file (testimonials.php) and putting a simple include <?php include (TEMPLATEPATH . ‘/testimonials.php’); ?> to call the page. This is working, but when I enter the below code nothing show up!? Not sure why….

<?php
query_posts(array('post_type' => 'Testimonials', 'orderby' => 'rand', 'showposts' => 1));
if (have_posts()) :
while (have_posts()) : the_post(); ?>
<h1><a>"><?php the_title(); ?></a></h1>
<?php the_content(); ?>
<?php endwhile;
endif; ?>
