With these two scripts Helpful can be used as short code on archive pages. Place the code in your functions.php to make it work.
In the first script the_content is manipulated and in the second script the_excerpt. Use what you have in use.
Quick tip: Use get_post_type( $post ) to check if a particular post type is in use.
