Hi @Vasili
Can you please remove any variables from the equation completely?
You can do this by harcoding the $post_id parameter of the get_field function like so:
$value = get_field('field_name', 123);
Where 123 is the post ID where you want to load the data from.
If ACF can’t load data like this, then the chosen post does NOT contain the data you expect and you will need to double check all your field names / post ID’s are correct.
Thanks
