Shortcode in template page

Hi there!

I’ve just installed the plugin and i love it!
Everything works, i’ve got only a small issues.

I would like to insert one form in a a specific part of my template. Reading another 3d i’ve founded this snippet:

<?php echo Caldera_Forms::render_form('CF553a5352266f9'); ?>

Is it correct? Because i’ve insert it (changing the form id) but i’ve got an error:

Permission denied or entry does not exist.

Anyone know how to fix this?

Thank you!
