             while ($records =  mysql_fetch_array($result)){
                    $poDateRetrieved = $records['date'];
                    $poDate=date("m-d-Y", strtotime($poDateRetrieved));

                   echo "<tr>

                     <td>$poDate</td>
                     <td>{$records['supplier']}</td>
                     <td>{$records['tAmount']}</td>

what if you type something wrong by mistake?
shouldn't you use the form <input type="date"> field? that way you can select the date
