nested region - losing display order

[Jim_Madrid]

I have a nested region that is giving me a giving me one glitch.

This is what I am getting when I display the results:

Phylum
.......Clase1
..............Order1
.....................Family1
..............................Species 1
..............................Species 2
.......Clase2
.............Family2
....................Species3

Because there was NO (animal) Order in the db for Species 3 it changed the display order.

I need it to read as follows where even though there is no value for Order it still retains the positions of the earlier species:

Phylum
.......Clase1
..............Order1
.....................Family1
..............................Species 1
..............................Species 2
.......Clase2
.....................Family2
..............................Species3

Below is the query I am using and following that the nested region statements

$base_phylum = ''; 
$base_clase = ''; 
$base_orden = ''; 
$base_familia = ''; 
$varphylum_rsspecies = "1";
if (isset($HTTP_GET_VARS['phylum'])) {
  $varphylum_rsspecies = (get_magic_quotes_gpc()) ? $HTTP_GET_VARS['phylum'] : addslashes($HTTP_GET_VARS['phylum']);
}
$varclase_rsspecies = "1";
if (isset($HTTP_GET_VARS['clase'])) {
  $varclase_rsspecies = (get_magic_quotes_gpc()) ? $HTTP_GET_VARS['clase'] : addslashes($HTTP_GET_VARS['clase']);
}
$varord_rsspecies = "1";
if (isset($HTTP_GET_VARS['orden'])) {
  $varord_rsspecies = (get_magic_quotes_gpc()) ? $HTTP_GET_VARS['orden'] : addslashes($HTTP_GET_VARS['orden']);
}
$varfam_rsspecies = "1";
if (isset($HTTP_GET_VARS['familia'])) {
  $varfam_rsspecies = (get_magic_quotes_gpc()) ? $HTTP_GET_VARS['familia'] : addslashes($HTTP_GET_VARS['familia']);
}
$vartax_rsspecies = "1";
if (isset($HTTP_GET_VARS['especie'])) {
  $vartax_rsspecies = (get_magic_quotes_gpc()) ? $HTTP_GET_VARS['especie'] : addslashes($HTTP_GET_VARS['especie']);
}
mysql_select_db($database_connFauna, $connFauna);
$query_rsspecies = sprintf("SELECT * FROM fauna WHERE phylum LIKE '%%%s%%' AND clase LIKE '%%%s%%' AND orden LIKE '%%%s%%' AND familia LIKE '%%%s%%' AND especie LIKE '%%%s%%' AND ('%s'!='' OR '%s'!='' OR '%s'!='' OR '%s'!='' OR '%s'!='') ORDER BY phylum, clase, orden, familia, especie ASC", $varphylum_rsspecies,$varclase_rsspecies,$varord_rsspecies,$varfam_rsspecies,$vartax_rsspecies,$varclase_rsspecies,$varphylum_rsspecies,$varord_rsspecies,$varfam_rsspecies,$vartax_rsspecies);
$rsspecies = mysql_query($query_rsspecies, $connFauna) or die(mysql_error());
$totalRows_rsspecies = mysql_num_rows($rsspecies);

and the nested region statements:

while($row_rsspecies = mysql_fetch_assoc($rsspecies)) 
{
$i=0; //used to now how much space you need. 
// assumes $row_rsspecies['clase'] / $row_rsspecies['orden'] etc 
if($row_rsspecies['phylum']) {
   if($base_phylum != $row_rsspecies['phylum']) { 
      echo str_repeat("<dd>",$i++).'Phylum'. " ". $row_rsspecies['phylum']; 
      $base_phylum = $row_rsspecies['phylum']; 
   } else {
      $i++;
   }
} else {
   $base_phylum = '';
}
if($row_rsspecies['clase']) {
   if($base_clase != $row_rsspecies['clase']) { 
      echo str_repeat("<dd>",$i++).'Clas'. " " .$row_rsspecies['clase']; 
      $base_clase = $row_rsspecies['clase']; 
   } else {
      $i++;
   }
} else {
   $base_clase = '';
}
if($row_rsspecies['orden']) {
   if($base_orden != $row_rsspecies['orden']) { 
      echo str_repeat("<dd>",$i++).'Ord'. " " .$row_rsspecies['orden']; 
      $base_orden = $row_rsspecies['orden']; 
   } else {
      $i++;
   }
} else {
   $base_orden = '';
}

if($row_rsspecies['familia']) {
   if($base_familia != $row_rsspecies['familia']) { 
      echo str_repeat("<dd>",$i++).'Fam'. " " .$row_rsspecies['familia']; 
      $base_familia = $row_rsspecies['familia']; 
   } else {
      $i++;
   }
} else {
   $base_familia = '';
}
echo str_repeat("<dd>",$i++).$row_rsspecies['especie'].'<br />'; 
}

Any help on this would be greatly appreciated.....
