This udemy course for newbies isn't working

Sharing is caring. So I'm posting this message.

I am doing the Udemy course, "Understanding the Steem economy course..."
And the 5.th section, which gives us an assignment.
Expect that it's not letting me pass on the next section.

Now, can someone tell the support team, or Hive account@paulag to please address this issue from now on?

I would really like to continue with the course, but I'm facing great difficulties.

I thank for any assistance with this issue in advance.
