Question

i am using joomla 2.5 and i want to create some tests for my students, so that's why i just downloaded JQuarks plugin and installed. But when i go to Components/JQuarks through administration panel it shows me this error!!
Fatal error: Call to a member function getUserStateFromRequest() on a non-object in administrator\components\com_jquarks\models\quizzes.php on line 60
So, i go to on line 60 .
Here's the code:
function getQuizzes()
{
if (empty( $this->_quizzes ))
{
global $mainframe ;
$context = 'com_jquarks.quizzes.list.' ;
$limit = $mainframe->getUserStateFromRequest('global.list.limit', 'limit', $mainframe->getCfg('list_limit'), 'int' );
$limitstart = $mainframe->getUserStateFromRequest( $context.'limitstart', 'limitstart', 0, 'int') ;
$this->_filter_order = $mainframe->getUserStateFromRequest( $context.'filter_order', 'filter_order', 'title', 'cmd' );
$this->_filter_order_Dir = $mainframe->getUserStateFromRequest( $context.'filter_order_Dir', 'filter_order_Dir', '', 'word' );
$orderby = '' ;
if($this->_filter_order_Dir) {
$orderby = ' ORDER BY '.$this->_filter_order.' '.$this->_filter_order_Dir ;
}
$query = ' SELECT quizzes.*, g.name AS groupname' .
' FROM #__jquarks_quizzes AS quizzes' .
' LEFT JOIN #__groups AS g ON g.id = quizzes.access_id' .
$orderby ;
$total = $this->_getListCount($query) ;
jimport('joomla.html.pagination') ;
$this->_pageNav = new JPagination( $total, $limitstart, $limit ) ;
$this->_db->setQuery($query) ;
$this->_quizzes = $this->_getList( $query, $this->_pageNav->limitstart, $this->_pageNav->limit );
if ($this->_db->getErrorNum()) {
return false;
}
}
return $this->_quizzes ;
}
Please help to fix this problem!!!
Thanks in advance.

I fixed a problem. Problem is the version of the Jquarks plugin was 0.2.4 and my joomla's version is 2.5. So i looked up from internet ,JQuarks 0.2.4 is for joomla 1.5 version not for joomla 2.5 . Then i just downloaded another plugin called ARI Quiz Lite to create some exams for my students. This plugin is for joomla 1.5,2.5 and 3.0 . Now its working.....:)
