I have this code snippet

```
<td width="143"><b>Monday</b></td>
<td width="68" class="open select_open">
  <span class="jqTransformRadioWrapper">
    <a href="#" class="jqTransformRadio" rel="radio_m"></a>
    <input type="radio" name="radio_m" checked="checked" class="jqTransformHidden">
  </span>
</td>

```

The radio button has no value. However, I should be able to change the value of the class attribute of the `<a>` tag and the `<td>` tag above the radio button when it's checked.

Could someone help me with this please?
