Show posts to 2nd author

Hello,

I’m trying to show posts to the second assigned author. Currently, the posts only show to the primary author.

I’ve searched the forum and found this code:
?php $user_name = get_the_author_meta(‘user_login’);
$args = array(‘post_type’=>array(‘product’),
‘tax_query’ => array(
array(
‘taxonomy’ => ‘author’,
‘terms’ => $user_name,
‘field’ => ‘name’,
)
),
‘posts_per_page’ => -1, ‘orderby’=> ‘title’, ‘order’ => ‘ASC’);
query_posts($args);
//the loop start here
if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

<table style=”width:100%”>
<tr style=”border: none; “>
<th style=”width:18%; border: none;” valign=”top”>
<?php echo the_post_thumbnail(‘thumbnail’); ?>
</th>
<th style=”border: none;”>
“><?php echo the_title();?>
<br><br>
<?php the_excerpt();?>

I’m not sure if this should go into a page template, when I did that, I got a blank page.

Thank you in advance for your time!
