Just want to make sure that this is exactly what your code looks like:
<?php
mypost = array(
‘post_type’ => ‘listing’,
‘posts_per_page’ => 20,
‘meta_key’ => ‘revenue_number’,
‘orderby’ => ‘meta_value_num’,
‘order’ => ‘DESC’
); $loop = new WP_Query( $mypost ); ?>
If it is then you’re missing a $
in front of mypost
on the first line.
