       // calling jQuery function

       </option>
       
       

       </select>
       
    

       </td>
       
   

       </tr>
       

       </table>
       

       </body>
       

       </html>
      

     
 
In IE 7, I'm getting a javascript error saying exception thrown and not caught.
