Display value of custom field not working

I am simply trying to print the value of a custom field. I have read all the documentation, tried out other people's suggestions, and nothing works. I can get it to print the ID #, but not the actual value I have in the field. I am using the Types plugin to create the field.

this prints the ID:

?php echo get_the_ID($value, 'authorinfo', true); ?

as well as:

?php echo get_the_ID($key, 'authorinfo', true); ?

this does nothing:

?php get_post_meta( $post-ID, 'authorinfo', true ); ?

this does nothing:

?php echo get_post_meta(get_the_ID(), 'authorinfo', true); ?

(I have a separate question on this site where the problem came up and a solution was offered but unfortunately it didn't work for me) - Display custom post type and custom fields within a Bootstrap Carousel

Here is all the code I'm working within in case that helps. I hope I'm doing something stupid here.

?php if (have_posts()) : while (have_posts()) : the_post(); ?

    div id="myCarousel" class="carousel"
        div class="carousel-inner"

          ?php $the_query = new WP_Query(array(
            'post_type' = 'testimonial', 
            'posts_per_page' = 1 
            ));
            while ( $the_query-have_posts() ) : $the_query-the_post(); ?
            div class="item active" data-title=""
                div class="slide-copy"
                    ?php the_content();?
                    span class="byline"?php echo get_post_meta(get_the_ID(), 'authorinfo', true); ?/span
                /div
            /div
            ?php endwhile; wp_reset_postdata(); ?
            ?php $the_query = new WP_Query(array(
            'post_type' = 'testimonial', 
            'posts_per_page' = 5, 
            'offset' = 1 
            ));
            while ( $the_query-have_posts() ) : $the_query-the_post(); ?
            div class="item" data-title=""
                div class="slide-copy"
                    ?php the_content();?
                    span class="byline"?php echo get_post_meta(get_the_ID(), 'authorinfo', true); ?/span
                /div
            /div

            ?php endwhile; wp_reset_postdata(); ?
          /div
        /div
      /div!-- end myCarousel --

?php endwhile; ?

EDIT/ADDITION

Since working with the Types plugin more, I am pretty sure this problem could be solved by using "types_render_field" instead of "get_post_meta". I don't have a place where I can test this, but I think this should help someone with a similar problem.

Easier than that! Just do:

echo types_render_field("description");

Where the "description" is the name of the custom field. This will print the value of "description" of your post / post type.

Here is this documentation of Wordpress Types plugin: http://wp-types.com/documentation/user-guides/displaying-wordpress-custom-fields/#1

This only works for "types plugin". If you are using "Advanced custom fields plugin" you should use: 

echo get_field('description');

The Types plugin is making this about 10x harder than it needs to be, you'll have to look through their documentation on the issue, but from what I can tell they don't store items in the postmeta table in a straightforward way. I created a simple field with the plugin in a sandbox env and the meta_key for a field I named data was wpcf-data. You may want to take your post ID and do this in your DB:

SELECT * FROM wp_postmeta WHERE post_id = NNNN;

where NNNN is your post ID. You may see a wpcf-authorinfo key, that is likely then the key you should be passing to get_post_meta:

echo get_post_meta(get_the_ID(), 'wpcf-authorinfo', TRUE);

I would try:

echo get_post_meta( $the_query->post->ID, 'authorinfo', true);

although I do agree with Mridul Aggarwal that 

<?php echo get_post_meta(get_the_ID(), 'authorinfo', true); ?>

should also work.
