tweaking of existing snippet – help needed

Hi, I am using this snippet to keep several cpt’s on one page for the Add Listing page, and a separate Add Events page:

/** Add Listing w all CPTs minus events */
add_action('geodir_before_detail_fields', 'geodir_add_listing_before_detail_fields', 0);

function geodir_add_listing_before_detail_fields(){
	
	global $post; 
	
	$current_posttype = geodir_get_current_posttype();
	
	$geodir_allow_posttype = get_option('geodir_allow_posttype_frontend');
	
	$post_types = geodir_get_posttypes('object');
	
	$addlisting_links = '';
	
	if ($current_posttype!="gd_events") {
	

//test if the key is in the array
//	if (in_array("gd_event", $geodir_allow_posttype)) {
//			    echo "trovato evento";
//
//$filtraevento = array( 1 );
//
//
//			}

//remove the position 1 (gd events from the new array)
			$filtraevento = array( 7 );
			
			$filtrato = array_diff_key( $geodir_allow_posttype, array_flip( $filtraevento ) );

	foreach($post_types as $key => $postobj){
		if(is_array($filtrato) && in_array($key, $filtrato) && count($filtrato) > 1){
		
			$name = $postobj->labels->singular_name;
					$checked = '';
			if($current_posttype == $key) 
				$checked = 'checked="checked"';
			
			$add_link = geodir_get_addlisting_link( $key );
			$addlisting_links .= '<div style="display:block;line-height:30px; margin-right:14px; float:left;">';
			$addlisting_links .= '<input type="radio" '.$checked.' value="'.$add_link.'" title="'.ucfirst($name).'" name="geodir_select_add_listing[]"  onchange="javascript:window.location=this.value;" >'.ucfirst($name);
			$addlisting_links .= '</div>';
			
		}
		
	}	
	
	
	if($addlisting_links != '')	{
					if($current_posttype != "gd_event") { 
		 ?>
		<h5><?php _e('Select Listing Type', GEODIRECTORY_TEXTDOMAIN); ?></h5>
		
		<div class="geodir_form_row clearfix">
			<div id="geodir_showposttypes" class="geodir_showposttypes">
			<?php echo $addlisting_links;?>
			</div>
		</div> <?php
		
	}
 	
}
}
}

I have added a new cpt, Announcements, that I would like to show on the Add Event page. As of now, it is showing on the Add Listing page. Anyone interested in tweaking it?
Thanks!
