maybe this is a very stupid question, but I'm quite the noob when it comes down to this.
So basically, I have a site running CMSMS and totally love how I can do almost anything with it without having to be a programmer

My site is about ceramics and workshops, and the idea is customers can subscribe to a workshop via the system (I found a partner for this).
So I want to to integrate a calendar in my cmsms installation, and the partner gives several options. One is an iframe, but that's totally ugly.
The other one is with this:
<?php print file_get_contents('https://www.myreservations.nl/calendar. ... 7e01dc7079'); ?>
Now I tried to modify a template (I made a copy of an existing one and am working on this copy.
So in the block content I tried doing this:
{block name='content'}
<div class="column row text-center">
<h3>{title}</h3>
<?php print file_get_contents('https://www.myreservations.nl/calendar. ... 7e01dc7079'); ?>
</div>
{/block}
which if probably totally idiotic, I know, but it was worth a shot.
Anyone of you know how I would be able to integrate this into my website and not having to resort to an iframe?
Thank you very much in advance.
