I have custom post type Named Trips , Taxonomy > Destination , Region Activity Etc.

Region Terms are , Annapurna , Everest etc. Activity Terms are trek, hiking, tours etc.

I made an archive template called taxonomy-region.php to show all activities under Region. But it should show all activities inside region template categorically but its not working properly.

Here is my code for taxonomy-region.php

<?php
/**
 * Template Name: Region
 *
 * @package WordPress
 * @subpackage Twenty_Fourteen
 * @since Twenty Fourteen 1.0
 */

get_header(); 
$custom_post_id = get_the_ID();
?>

<style type="text/css">
  section.country-bg {
    height: 555px;
}
</style>


<?php

$taxonomyslug = get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) );
$term = get_queried_object();
$image = get_field('region_taxonomy_image', $term);

$description = get_field('region_taxonomy_description', $term);

?>
<section class="country-bg" style="background:url(<?php echo $image ?>);background-size:cover;
background-repeat: no-repeat;">
