In Reading Data from Databases with SQL. The two last challenges are not working. ex "Dealing with NULL"

I'm having issues with the Database foundation section under Reading Data from Databases with SQL. The two last code challenges aren’t working. Here’s a screen shot of the error I get:

My answers to the “Dealing with NULL” challenge is:

 SELECT * FROM movies WHERE year IS NULL;

I suppose everything is correct. Or am I doing something wrong? Can somebody help me or give me a hint on what to do. Please, I have been stuck on this section for 2 days, but I think it is a problem with the website.

Your query worked for me (and the corresponding one for the second challenge):

SELECT * FROM movies WHERE year IS NOT NULL;

Also worked without the semicolon at the end.

You might want to email help@treehouse.com with a link to the challenges (https://teamtreehouse.com/library/database-foundations/reading-data-from-databases-with-sql/dealing-with-null) and your screenshot above to report a bug.
