HTML Stops after I execute a PHP while loop

[numpy]

As the title states, I have a while loop, and after the loop the markup stops.
here is the index.php:

<?php
include "header.php";
?>
<div id="nav">
    <ul id="nav">
        <li><a href="#">Course</a></li>
        <li><a href="#">Overview</a></li>
        <li><a href="#">FAQs</a></li>
        <li><a href="#">Contact</a></li>
        <li><a href="#">Login</a></li>
    </ul>
  </div>
<div id="contentwrapper">
    <div id="contentcolumn">
        
    <div class="innertube">
        <b>Training Content: </b> 
        <hr />
        <?php if($_GET['view']=="player"){?>
        <p class="player"><a  
             href="http://pseudo01.hddn.com/vod/demo.flowplayervod/flowplayer-700.flv"
             style="display:block;width:520px;height:330px"  
             id="player"> 
        </a> </p>
        <script> 
            flowplayer("player", {src:"ICI_ProcessApplicatonImages.swf", width:750,height:400});
        </script> 
        <?php }elseif($_GET['view']=="pp"){ ?>
                <iframe src="ICIPPS/ICIProcessApplicationImages.html" width="800px" height="460px"></iframe>
        <?php }elseif($_GET['view']=='first'){ ?>
            Welcome to ICI Training
            <?php }?>
    </div>
    </div>
</div>

<div id="leftcolumn">
    <div class="innertube">
        <b>Links</b>
        <hr />
<?php while($row = $links->fetch_assoc()){ ?>
<div id="navigation">
    <ul>
<?php echo"<li><a href=" . $row['location'] . ">" . $row['name'] . "</a></li>";}?>
            </ul>
                </div>    
            </div>
        </div>

</div>

Here is where it stops

<div id="rightcolumn">
<div class="innertube">
        <b>Refferences</b>
        <hr /> 
        asdkfasjdfkahsdfa
        sdfasdkfjasd;lfkjas'ldkfjasldasd
        fasdfkljasdflkjasdfas
        dfasldfkjasdlfkjasdf</div>
</div>

<?php include "footer.php";?>

I have done this same thing in numerous other sites, its just odd to me. Let me know if more is needed.

Nevermind....I figured it out. Silly, SILLY me. I had the <div for navigation INSIDE the loop... so it was well, looping. Thereby killing the rest of the markup.

Hahaha, I see it. Be careful.
