Portfolio page scrollspy problem

Hi there!

I’m trying to get the navbar buttons to change their active state when scrolling through my portfolio page, but it’s not working. Can someone tell me what I am doing wrong or missing?
Here’s the link to my portfolio page:

Thanks in advance!

You included wrong URL in Javascript Pen settings. Use this one: https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js

Of course, it had to be a mistake like that.:sweat_smile: Thanks a lot!
