Ads between categories in Arras theme

Hi.

I need to put this code:

<?php echo adrotate_group(1); ?>

inside this code:

public function register_sections() {

/*$this->add_section( 'slideshow', 'home', array (
			'label'		=> __( 'Slideshow', 'ar2' ),
			'title'		=> __( 'Slideshow', 'ar2' ),
			'type'		=> 'slideshow',
			'count'		=> 6,
			'priority'	=> 12,
			'display_types' => array( 'slideshow' ),
			'enabled'	=> true,
		) );*/
		$this->add_section( new AR2_PostViews_Slideshow_Section( $this, 'slideshow', 'home', array (
			'label'		=> __( 'Slideshow', 'ar2' ),
			'title'		=> __( 'Slideshow', 'ar2' ),
			'type'		=> 'slideshow',
			'count'		=> 6,
			'priority'	=> 12,
			'display_types' => array( 'slideshow' ),
			'enabled'	=> true,
		) ) );

                $this->add_section( 'news-posts', 'home', array (
			'label'				=> __( 'News Posts', 'ar2' ),
			'title'				=> __( 'Latest News', 'ar2' ),
			'type'				=> 'line',
			'count'				=> 6,
			'priority'			=> 11,
			'enabled'			=> true,
		) );

		$this->add_section( 'featured-posts-1', 'home', array (
			'label'		=> __( 'Featured Posts #1', 'ar2' ),
			'title'		=> __( 'Featured Posts', 'ar2' ),
			'type'		=> 'node',
			'count'		=> 6,
			'priority'	=> 10,
			'enabled'	=> true,
		) );

Between categories.

If I use it this way:

$this->add_section( 'news-posts', 'home', array (
			'label'				=> __( 'News Posts', 'ar2' ),
			'title'				=> __( 'Latest News', 'ar2' ),
			'type'				=> 'line',
			'count'				=> 6,
			'priority'			=> 11,
			'enabled'			=> true,
		) );
		echo adrotate_group(1);
		$this->add_section( 'featured-posts-1', 'home', array (
			'label'		=> __( 'Featured Posts #1', 'ar2' ),
			'title'		=> __( 'Featured Posts', 'ar2' ),
			'type'		=> 'node',
			'count'		=> 6,
			'priority'	=> 10,
			'enabled'	=> true,
		) );

My ads appears at the top of the homepage.
In home.php is just placed this code:

<?php ar2_render_zone( 'home' ) ?>

So, not possible to add it in home.php

I am new, so I would appreciate any help.
