Ciao, ho fatto così ma non mi esce per niente bene....non so a questo punto se ho capito bene....
Ho tolto le stringhe sql per non inserire troppe cose


codice HTML:
<table width="900" border="0" cellpadding="3" class="TableClienteImm" >
    <thead>
  <tr>    
<th colspan="6"><img src="images/invoices.gif" alt="" width="16" height="16" /> Dati Immobile</th>  
</tr>  
</thead>
  <?            
            $result5 = mysql_query($SQL5) or die("Couldn?t execute query.".mysql_error());                                    

          $result9 = mysql_query($SQL9) or die("Couldn?t execute query.".mysql_error());                            

            $resultcount = mysql_query($SQLcount) or die("Couldn?t execute query.".mysql_error());                
$row_count = mysql_fetch_array($resultcount);                
$count = $row_count['count'];

            if (mysql_num_rows($result5) > 0) {
                echo "<ul>";                                
while($row5 = mysql_fetch_array($result5,MYSQL_ASSOC)) {
while($row9 = mysql_fetch_array($result9,MYSQL_ASSOC   {
