Cant get Carousel to Work

My pen:

Carousel not working despite me including Bootstrap and Jquery directly into the head tag as suggested by some people on this page.

Can you please review and let me know.

Put this in your head:

<script src="" integrity="sha384-JZR6Spejh4U02d8jOt6vLEHfe/JQGiRRSQQxSfFWpi1MquVdAyjUar5+76PVCmYl" crossorigin="anonymous"></script>

You are using old bootstrap 3.3.7, just put a new version of bootstrap 4.0.0


Wow I feel stupid now, thanks for that one.
