Nested Repeat Regions - Working but not as intended

Have created a nested repeat region using the Dreamweaver Developer Toolbox which works fine - however, this is for a menu system and only want the second repeat region to show where the Parent ID is the same as the Page ID...script:----------------------
HEADERS:
mysql_select_db($database_conn_Mm, $conn_Mm);
$query_master1navMenu = "SELECT * FROM navMenu WHERE parent IS NULL ORDER BY title";
$master1navMenu = mysql_query($query_master1navMenu, $conn_Mm) or die(mysql_error());
$row_master1navMenu = mysql_fetch_assoc($master1navMenu);
$totalRows_master1navMenu = mysql_num_rows($master1navMenu);

mysql_select_db($database_conn_Mm, $conn_Mm);
$query_detail2navMenu = "SELECT * FROM navMenu WHERE parent='123456789' ORDER BY title";
$detail2navMenu = mysql_query($query_detail2navMenu, $conn_Mm) or die(mysql_error());
$row_detail2navMenu = mysql_fetch_assoc($detail2navMenu);
$totalRows_detail2navMenu = mysql_num_rows($detail2navMenu);
?>

PAGE:
  <?php do { ?>
    <tr>
      <td><b><?php echo $row_master1navMenu['title']; ?></b></td>
    </tr>
    <?php if ($totalRows_master1navMenu>0) {
    $nested_query_detail2navMenu = str_replace("123456789", $row_master1navMenu['id'], $query_detail2navMenu);
    mysql_select_db($database_conn_Mm);
    $detail2navMenu = mysql_query($nested_query_detail2navMenu, $conn_Mm) or die(mysql_error());
    $row_detail2navMenu = mysql_fetch_assoc($detail2navMenu);
    $totalRows_detail2navMenu = mysql_num_rows($detail2navMenu);
    $nested_sw = false;
    if (isset($row_detail2navMenu) && is_array($row_detail2navMenu)) {
      do { //Nested repeat
?>
      <tr>
        <td>&nbsp;&nbsp;&nbsp;&nbsp;<?php echo $row_detail2navMenu['title']; ?></td>
      </tr>
      <?php
      } while ($row_detail2navMenu = mysql_fetch_assoc($detail2navMenu)); //Nested move next
    }
  }
?>
    <?php } while ($row_master1navMenu = mysql_fetch_assoc($master1navMenu)); ?>
-----------------------------------
This shows the submenus, but constantly - I only want the submenus to appear when the parent ID set in the database is equal to the URL variable '?id=X'

Can get it to show only the submenus that have the parent ID, but it shows them under all menu links.

Any advice??
