Java Script to access table cell data

Please refer to the code below in relationship to this problem.

How Can I extract the value of cell data From a table. When the cell data is defined as a Input=Text I can do it.

If I load the table cells with variables I cannot access the data.

If this is possible Please Help.

<!– *** ADD CART ***–>
function add_cart (obj,index)
{
alert(“got to add cart”);
var qindex = eval(‘document.Iform.Mfgqty_’+index);
alert(qindex.value);

window.open(“/infcgilibp/isl550.pgm?mfgno=/%mfgnum%/&mfgdes=/%mfgdesc%/&mfgqty=”+qindex.value,
“Iform1”, “scrollbars,status,top=10,left=70,height=500,width=760”);

return;
}

<tr>
<td><FONT size=”-1″><a name=”/%Mfgx%/”>/%Mfg%/</a></FONT></td>

<td><FONT size=”-1″>/%Mfgdesc%/</FONT></td>

<td><FONT size=”-1″>/%Mfgnum%/</FONT></td>

<td><FONT size=”-1″>/%Mfgprice%/</FONT></td>
<td><FONT size=”-1″><INPUT size=”4″ type=”text” maxlength=”4″ name=”/%Mfgqty%/”></FONT></td>
<td valign=”middle” align=”center”><FONT size=”-1″><A href=”javascript:add_cart(/%xxx%/);”>Add</A></td>
</tr>
