The relationship in View thru Shortcode doesn't get shown

Hi,

I have a relationship from client to country. Works nicely, also in View / Singular.
It's just that in the View / Shortcode I can't get the country to be shown.

{% set args = { post_type: 'fan', posts_per_page: -1, orderby: 'title', order: 'asc' } %}
{% set posts = mb.get_posts( args ) %}

<table>
<tbody>
<tr>
	<th><strong>Fan ID</strong></td>
	<th><strong>Name</strong></td>
	<th><strong>Country</strong></td>
	<th><strong>Action</strong></td>
</tr>
{% for post in posts %} 
	<tr>
		<td>{{ post.title }}</a></td>
		<td>{{ post.name }}</td>
		<td>{% set relationship = mb.attribute( relationships, 'fan-countrydetails' ) %}
		{% for post in relationship.to %}
			{{ post.post_title }}
			{{ field }}
		{% endfor %}</td>
		<td class="middle"><a href="https://staff.ladyfatale.com/fan-details/?rwmb_frontend_field_post_id={{ post.ID }}" rel="">[icon name="pencil-alt" style="solid" class="middle" unprefixed_class="middle"]</a>   <a href="https://staff.ladyfatale.com/fan/{{ post.title }}" rel="">[icon name="eye" style="regular" class="middle" unprefixed_class="middle"]</a></td>
	</tr>
{% endfor %}
</tbody>
</table>

Can you please advise?
Thanks!
