Placing the contents of a block in any location

Drupal Newbie question:
I'm experimenting with Drupal on a new site (http://www.game-boyz.com/drupal-4.7.2/ ) trying to show off a segment from menu (the Platforms). I have that built as a menu item that I've added to the left side bar block). I would rather add this menu item elsewhere on the page.

I tried this code:

<?php
  $block = module_invoke('menu', 'list', 'view', 104);
  $output = "<div class=\"front-page-block\">\n";
  $output .= "<div id=\"front-block-title\"><h2>".$block['subject']."</h2></div>\n";
  $output .= "<div class=\"content\">".$block['content']."</div>\n";
  $output .= "</div>\n";
  print $output;
?>

That doesn't work. What is the right syntax for adding a menu a spot on the theme?

Thanks in advance,

All the best,

Mike
