I'm building a theme where specific pages pull only one category to display in a list of the loop. I'm trying to specify only one category per custom page, but the loop seems to be pulling in all of the posts still
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<div class="entry col3">
<?php the_content(); ?>
<?php $custom_query = new WP_Query('cat=6'); // only category 6 music posts
while($custom_query->have_posts()) : $custom_query->the_post(); ?>
<div <?php post_class(); ?> id="post-<?php the_ID(); ?>">
<h1><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h1>
<?php the_content(); ?>
</div>
<?php endwhile; ?>
<?php wp_reset_postdata(); // reset the query ?>
</div>
