## Using an ACF field from a page within a post loop?

Question

I have a page set up with custom fields using Advanced Custom Fields. One of the fields is a text field for specifying the text for a read more button. Within the page template I have a post query to pull in a post and I would like to use the ACF field for the “Read More” text within this loop. However, because the ACF field is associated with the page, it doesn’t work when I am trying to call it from within the post loop:

<?php query_posts('showposts=1&post_type=post&cat=1'); if ( have_posts() ): ?>
<?php while ( have_posts() ) : the_post(); ?>
<h4><?php the_title(); ?></h4>
<p><?php the_excerpt(); ?></p>
</div>
