X completion doesn?t work

Hi to all.
I’ve just finished the course Learn javascript by building a Role Playing Game. At the last step I have submitted the result to X, after having created an account. Yet, it looks like I haven’t submitted it. What am I wrong with?

I am not sure I understand your question, what step are you on? What’s happening?
Remember that to complete a step you need to pass the tests and then use the “Submit” button.

I apologize. I believed X was the only final task.

What is ‘X’? I seriously don’t know what that is
