Using WP_Query with multiple conditionals

Hey There,

I’d like to create a list of post titles. The posts need to be part of a category called “Job Openings” and a custom field called position_status needs to be “Open”. I know how to generate a list based on the category:

<ul class="news-list">
  <?php
$pstatus = get_post_meta($post->ID, 'position_status', true);
$my_query = new WP_Query('category_name="Job Openings"');
  while ($my_query->have_posts()) : $my_query->the_post();
  $do_not_duplicate = $post->ID; ?>
    <li><?php the_title(); ?> <a href="<?php the_permalink(); ?>">Read More &raquo;</a></li>
  <?php endwhile; ?>
</ul>

That will display everything in the category “Job Openings” in a nice list just fine but I’m not sure how to filter that query so the custom field position_status is set to “Open”.

Any ideas? Thanks in advance!
