Ok, I solved it.
I could not see anything because I had not added the button status in the configuration of my checkout.
I also had to change the status file to hide its display in the checkout process and leave it visible where I needed.
This is the modification in the "status" file of the view "checkout":
<?php
/**

*/
defined('_JEXEC') or die('Restricted access');
?><!-- <br/>
<span id="hikashop_checkout_status">
<?php
$array=array();
if(!empty($this->shipping_data)){
$array[]= JText::sprintf('HIKASHOP_SHIPPING_METHOD_CHOSEN', '<span class="label label-info">'.$this->shipping_data->shipping_name.'</span>');
}
if(!empty($this->payment_data)){
$array[]= JText::sprintf('HIKASHOP_PAYMENT_METHOD_CHOSEN', '<span class="label label-info">'.$this->payment_data->payment_name.'</span>');
}
echo implode('<br/>',$array);
?>
</span>
<div class="clear_both"></div> -->
I only insert comment before and after the html tag.
Thaks for great and fast support
