                          </tr>
                           <tr class="td2">
                    <td>&nbsp;</td>
                    <td >Pets Allowed : </td>
                    <td ><input class="textfeild1" type="checkbox" name="petslong" id="petslong" value="Pets" <? if($petslong==1) echo "checked='checked'";?>/></td>

                    <td><input class="textfeild1" type="checkbox" name="poollong" id="poollong" value="Pool" <? if($poollong==1) echo "checked='checked'";?>/></td>
                    <td align="right">&nbsp;</td>
                  </tr>
                       <tr class="td2">
