Go to next lesson in the curriculum

I am sorry to be so basic here, but…
I just started JavaScript. The first lesson is entering comments.
I do that and click “run the tests”, (with no results returned, as they are just comments).

But then there is no “Next” to get to the next lesson in JavaScript (which is declaring variables).

How do I keep going to each next lesson in the JavaScript Curriculum

Thank you!

The challenge tests do not work well on Safari, Edge, or Internet Explorer. The curriculum works best when using Chrome.
