Difficulty With WordPress Function

I’m using the following code to display: Welcome, Username along with a profile link next to it. However, the profile link gets echoed over and over again. I found it under my branding div and blog title div in thematic. Anyone know why it is showing up all over the header?

<?php
      if ( is_user_logged_in() ) {
      global $current_user;
      get_currentuserinfo();

      echo 'Welcome,  ' . $current_user->display_name . '!' . "\n";
      echo '<li><a href="/profile">Profile</a></li>'; 

      }
      else {
      wp_register();
      }

?>
