How can I go to the Next?

I am the first time to Codecademy. Here is very great! And I am a engineer with few experience in programming.

I want to star from HTML. In the 1st exercise “What is HTML” ,

It’s very easy, right?

I think I have typed my name into the code correctly. But I got a WRONG mark. And there is a hint : $expect is not defined

Now I can not push the Next button to 2nd exercise.

I can not understand why? Need I level up to Pro?

Thank you for your help.

I reported bug and now I can go to the Next Exercise.:smile:

I often get WRONG mark in instructions, is there any relationship with the speed of local internet?
