webform alter default value template.php I need to alter the default value of a webform in d6, so in my template.php I insert the following function, but it does not work; I don't like to use $get in webform.

function themename_form_alter(&amp;$form, &amp;$form_state, $form_id) {
  if ('webform_client_form_id' == $form_id) {
    $form['id_of_input']['#default_value'] = $node-&gt;field_cck_value[0]['value'];
    return $form;
  }
}


Can you help me?
Webform is a node module. So editing a node even though it contains form can be altered using hook_nodeapi.
