forum tråd. hjælp til at opsætte nogle if's

Det her bliver lidt indviklet, men jeg håber der er nogen der gider hjælpe, for jeg er kørt helt fast i det.

Som det kan ses, så har jeg problemer med at få de linjer mellem svarerne til at passe.

Sådan ser koden ud:

    <?php
function show_comment($parent,$tael) {
  $rs = mysql_query(sprintf("SELECT dato, space, answerID, user, replyID,comment FROM reply WHERE answerID = %d",$parent));
  while($row = mysql_fetch_array($rs)) {
    $result = mysql_query("SELECT answerID FROM reply WHERE answerID = $row[replyID]");
    $num_rows = mysql_num_rows($result);
    //echo $num_rows;
    if(($num_rows > 2)? $border2 = 'border-left:solid 1px #FFF;': $border2 = 'border-left:solid 1px #CCC;');
    if($row[answerID] == "0"){
?> 
<table width="100%" cellpadding="2" cellspacing="0" style="border:solid 1px #666; margin-top:2px; background-image:url(nameBarBack.gif); background-repeat:repeat-x;">
  <tr>
    <td><span class="style2">
      <?=$row[replyID]?>
    </span> # <span class="style1">
      <?=$row[user]?>
    </span></td>
  </tr>
  <tr>
    <td style="border-top:solid 1px #666;"><?=htmlspecialchars($row[comment])?><br />
    <div class="statusBar"><a href="java script:void(0)" >
    <img src="svar.gif" alt="Post" border="0" class="btn" onclick="answerPost('<?=$row[replyID]?>','Du%20besvarer%20<b><?=$row[user]?></b>');"></a></div>
</td>
  </tr>
</table>
<? show_comment($row['replyID'],$tael++); ?>
<?
}else{
?>
<table width="100%" cellpadding="0" cellspacing="0" style="">
  <tr>
    <td>
    <div style="margin-left:5px; width:5px; height:19px; border-left:solid 1px #CCC; border-bottom: solid 1px #CCC; float:left; margin-bottom:0px;"></div>
      <table width="100%" cellpadding="2" cellspacing="0" style="border:solid 1px #666; margin-top:2px;background-image:url(nameBarBack.gif); background-repeat:repeat-x;">
        <tr><td>
      <span class="style2">
      <?=$row[replyID]?>
      </span> # <span class="style1">
      <?=$row[user]?>
      </span>      </td>
        </tr></table>
    </td>
  </tr>
</table>
<table width="100%" cellpadding="0" cellspacing="0" style="margin-left:5px;<?=$border2?>">
  <tr>
    <td>
    <table width="100%" cellpadding="2" cellspacing="0" style="margin-left:5px; border-left:solid 1px #666; border-bottom:solid 1px #666; border-right:solid 1px #666;">
      <tr><td>
    <?=htmlspecialchars($row[comment])?><br />
    <div class="statusBar"><a href="java script:void(0)" >
    <img src="svar.gif" alt="Post" border="0" class="btn" onclick="answerPost('<?=$row[replyID]?>','Du%20besvarer%20<b><?=$row[user]?></b>');"></a></div>
    </td></tr></table>   
    <? show_comment($row['replyID'],$tael++); ?>
    </td>
  </tr>
</table>

<?   
        }
    }
}
show_comment(0,0);

?>

Håber nogen kan overskue det, og give lidt hjælp.
