$userdata->set()

[1Unreal]

I'm having some trouble setting options...

I have this

<input type="text" name="set_options[lastfm_username]" />

On modifyoptions template

This on profile_updateoptions plugin

PHP Code:

$vbulletin->input->clean_array_gpc('r', array('lastfm_username' => TYPE_NOHTML);
$userdata->set('lastfm_username', $_REQUEST['lastfm_username']); 


And this on userdata_start

PHP Code:

$this->validfields['lastfm_username'] = array(TYPE_STR, REQ_NO); 


But its not updating.
