    <tr>
        <td width="70" rowspan="2" align="center" valign="top" bgcolor="#000000" ><img src="<?php echo HTTP_SERVER;?>images/sok.jpg" width="70" height="50" /></td>
        <td width="200" align="left" ><select name="groupe1" class="listSize" id="markedslist">

    the answer is:

    Code:
     sub_cat.options[sub_cat.length] = new Option(sub_cat_array[i][1],sub_cat_array[i][2]);
    instead of:

    Code:
    sub_cat2.add(opt2,opt2.value);
