QF SmartyArray with radio buttons

Hi, I'm converting old QF (2.x) code so it can work with QF 3.x and make use of the SmartyArray renderer. I'm a bit puzzled as to why the following code gives me notices. I'm runnig Smarty 2.6 and the latest stable quickform 3.2.1). <?php require 'HTML/QuickForm.php'; require 'HTML/QuickForm/Renderer/ArraySmarty.php'; require 'Smarty/Smarty.class.php'; $form = new HTML_QuickForm; $smarty = new Smarty; $renderer =& new HTML_QuickForm_Renderer_ArraySmarty($smarty); $institutions = array(

   "1"    =>    "Number One",
   "2"    =>    "Number two",

); foreach ($institutions as $instID => $instName) { $radio[] = &HTML_QuickForm::createElement('radio', null, null, 'Yes', 'yes'); $radio[] = &HTML_QuickForm::createElement('radio', null, null, 'No', 'no'); $form->addGroup($radio, 'conn_allowed['.$instID.']'); unset($radio); } $form->accept($renderer); ?> What I hope to achieve is HTML output that looks like this: <table> <tbody> <tr>

     <td> </td>
     <th nowrap="nowrap"> Can connect to NREN </th>

</tr> <tr>

     <td> Universities </td>
     <td style="text-align: center;"> <input value="yes" type="radio" name="conn_allowed[1]"
                 checked="checked">
       Yes
       <input value="no"
                 type="radio" name="conn_allowed[1]">
       No </td>

</tr> <tr>

     <td> Institutes of higher/further education </td>
     <td style="text-align: center;"> <input value="yes" type="radio" name="conn_allowed[2]"
                 checked="checked">
       Yes
       <input value="no"
                 type="radio" name="conn_allowed[2]">
       No </td>

     <td> Research institutes </td>
     <td style="text-align: center;"> <input value="yes" type="radio" name="conn_allowed[3]"

</tr> </tbody> </table> note: above HTML was generated using QF 2.x without the use of any renderers. Any ideas on how I would be able to do that using QF3 and the Smarty renderer? Do I need a different renderer? TIA, Jeroen
