Custom Template to display data

HI
On the following page on our site https://www.caribbeanluxuryyachtcharters.com/luxury-yachts/motor-yachts-2/

I am trying to display information coming from a subscription database which would look like the information on this page: https://www.bvisail.com/motor-yacht-charter.php

However it is not doing so. I created a custom template, uploaded it and still cannot get it to work.

Any suggestions?

Thanks.
