How to make the shortcode work

Hello

I use the free version. I have only one template activated with the id : 1.
So I use the shortcode on my single.php template

<?php echo do_shortcode('[e2pdf-download id="1"]'); ?>

But nothing shows on the page. Can you help ?I wanted to buy the pro version but I ma not sure the pro version works.
Thanks

I forgot to precise something :

Template is set on custom post type.

Hi,

In case you need to use it via PHP call it must be defined "dataset" which is the custom Post ID for which it's need to generate PDF.

<?php echo do_shortcode('[e2pdf-download id="1" dataset="2"]'); ?>

<?php
$post_id = '2';
echo do_shortcode('[e2pdf-download id="1" dataset="'.$post_id.'"]');
?>
