Displying plugin on the theme

Yes,

Just add follwing php code

<?php
$instance=array('title'=>'Latest News','maxitem'=>5,'padding'=>5,'add_link_to_title'=>1,'show_content'=>1,'delay'=>5,'height'=>200,'scrollamount'=>1);
            $verticalScroll=new verticalScroll();
            echo $verticalScroll->widget($args=null,$instance);
?>

It seems to work, but I’m also getting an error just above the news items:

“Warning: extract() [function.extract]: First argument should be an array in /wp-content/plugins/vertical-news-scroller/newsScroller.php on line 589”
