Custom field in hyperlink, inside recent posts

I’m trying to “pull” a custom field into a hyperlink address. Problem is, I think I’m getting too deep in the coding. I pulled this code from WordPress Codex to display my recent posts by tag.

<?php
    $key = 'member-name';
    $tag = get_post_meta($post->ID, $key, true);
    $args=array(
	'numberposts' =>5,
	'tag' => $tag,
	'orderby' =>'post_date',
	'order' => 'DESC',
    );
$my_query = new WP_Query($args);
    if( $my_query->have_posts() ) {
	      echo 'Recent News:';
      while ($my_query->have_posts()) : $my_query->the_post(); ?>
        <li>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php
the_title_attribute(); ?>"><?php the_title(); ?
></a>
</li>
       <?php
      endwhile;
    } //if ($my_query)
  wp_reset_query();  // Restore global post data stomped by the_post().
?>

But now I want to add an RSS feed image next to Recent News, which isn’t a problem. It’s when I want to link that image to the page’s custom field that gets to be a problem. I have tried a number of combinations but this seemed to make the most sense to what I’m trying to do…but it doesn’t work.

<?php
    $key = 'member-name';
    $tag = get_post_meta($post->ID, $key, true);
    $args=array(
	'numberposts' =>5,
	'tag' => $tag,
	'orderby' =>'post_date',
	'order' => 'DESC',
    );
$my_query = new WP_Query($args);
    if( $my_query->have_posts() ) {
	      echo '<a href="../tag/<?php $key= "member-name"; echo get_post_meta($post_ID,$key,true); ?>/feed">
<img src="../wp-content/uploads/RSSfeed24transparent.png" /></a> Recent News:';
      while ($my_query->have_posts()) : $my_query->the_post(); ?>
        <li><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php 

the_title_attribute(); ?>"><?php the_title(); ?></a></li>

       <?php
      endwhile;
    } //if ($my_query)
  wp_reset_query();  // Restore global post data stomped by the_post().
?>

The problem arises with this part of the code:
<a href="../tag/<?php $key= "member-name"; echo get_post_meta($post_ID,$key,true); ?>/feed">
I have plugged in one of the values in the place of the php script, and I got what I was looking for. So I’m just wondering if I’m getting too deep in the code and need extra () or {} or something like that to help separate it?
