List categories with description

Hi, little problem… i need see a list of categories with title and description but dont see count article for categories. I use the widget in siderbar and i create this function:

function viewCategories()
{
	global $post;
	$args=array(
		'orderby' => 'name',
		'order' => 'ASC'
	);
	$categories=get_categories($args);
	foreach($categories as $category)
	{
    	echo '<p>Category: <a href="' . get_category_link( $category->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>' . $category->name.'</a></p> ';
    echo '<p> Description:'. $category->description . '</p>';
    //echo '<p> Post Count: '. $category->count . '</p>';
	}
}

the problem is that the output does not change anything.
