Button Not Appearing On Portfolio Page

I would like to have your buttons appear on 4 separate portfolio pages so that when clicked, the viewer goes back to the main folio page. I have tried placing this code everywhere on the 3-columnpage template, but to no avail. Can you please help me?

This is the code I used:
<?php echo do_shortcode(‘[maxbutton id=”1″]’); ?>

This is the main folio page:

This is one of 4 folio pages where I want the button to appear on the bottom:
http://www.derickbolinderinteriors.com/#!/contemporary-11

Thanks!
