Outputting new field for public view

I added a new “Region” field to my client’s database. The following PHP displays that but only in the WordPress admin area. My efforts to display Region on a public page all fail silently. Tried creating a shortcode but also silent failure.

add_action( 'single_job_listing_meta_end', 'display_job_region_data' );
function display_job_region_data() {
  global $post;
  $region = get_post_meta( $post->ID, '_job_region', true );
  if ( $region ) {
    echo '<li>' . __( 'Region: ' ) . esc_html( $region ) . '</li>';
  }
}

The page I need help with: [log in to see the link]
