please make the question clear Thanks.

This is not a question.

hes not putting a question he is just clarifying that there has been a typo at step 76, as he says U have to use userData. not UserData? as you are being told initially , it could be a typo or us not yet understanding when to use the “?” mark when it comes to these types of values , I believe in this case it should not be used because the value set is already null and 0 so u dont need it
