Why isn't my carousel sliding?

Why isn't my carousel sliding?


Hi, I’m trying to figure out carousels from the tutorial on ws3schools using Bootstrap 3. However, the carousel in this pen won’t slide and I can’t see where I’ve messed up. If someone could point out what I’ve done wrong I would appreciate it greatly because I can’t see it for the life of me.



add these:

  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>


Ah, thank you very much, this was driving me mad!
