this is my table:

<table border="0" cellpadding="0" cellspacing="0" style="width: 100%;">
                <tr>
                    <td align="right">
                        <a id="imgAddTC" href="javascript:__doPostBack('imgAddTC','')"><img border="0" src="images/icons/add_server.png" alt="Alternate Text" /></a>
                    </td>
                </tr>
                <tr>
                    <td>
                        <div id="divAddTC">
                            <table border="0" cellpadding="0" cellspacing="0">
                                <tr>
                                    <td>
                                        <input name="nothing" type="text" value="my Value" id="nothing" />
                                    </td>
                                </tr>
                            </table>
                        </div>
                    </td>
                </tr>
</table> 

am able to find the DIV(divAddTC) in the table but not able to find the INPUT TYPE (nothing) inside the table, have tried $(nothing).html() and $(divAddTC).find(nothing) and also $(divAddTC).find('table','tr','td').find(nothing) but all return Undefined, please advice me whats the correct way around.
