Slider not sliding, three slides appear and don't move

We installed the slider, but the three cells are not cycling. What are we doing wrong?

This is the shortcode we used:

[slick-carousel-slider category=”72″ limit=”3″ show_content=”true” dots=”true” arrows=”true” autoplay=”true” autoplay_interval=”1000″ speed=”1000″ effect=”true” loop=”true” image_size=”large”]

This is the site where the code is placed:

We would like the the slider to mimic this similar module:
