Embed in Template Function

I’m attempting to embed the slider into a home page template, but nothing is showing.

Here is what I’m looking at:

Shortcode:
[crellyslider alias=”homepage”]

The shortcode obviously doesn’t work in this situation so I tried the code on the documentation:

<?php if(function_exists(‘crellySlider’)) crellySlider(‘homepage’); ?>

No result. Am I changing the php code incorrectly?

Thanks!
