My dots were not navigating properly. I was allowed to pass the course, but the code is in error. There is an error in the example code in the beginning of the exercise. This error is replicated later in the instructions the file app.js, in the portion of the exercise dealing with the previous dots. The following is a copy of the code in error:
var currentSlide = $('.active-slide');
var prevSlide = currentSlide.prev(); <---ERROR
var prevDot= currentDot.prev(); <---ERROR
It should be method .previous().
There is also an error in the entire exercise because the "More" link does not appear on the page as referenced in the instructions.
I was able to find and fix the .previous() bug, but not the "More" link bug. Thought I would post in case anybody else runs into this bug.
