Hi, Martin! You're doing splendidly! But I have a feeling that you haven't really gotten into the idea of scope yet. That variable year only exists inside that function getYear. Once that function ceases to execute, the variable year goes "out of scope" or disappears. You no longer have access to it. This is why we have the return statement.

The reason it's saying that Task 1 is no longer passing is because there's an error in your code because of the year being undefined outside of the function and JavaScript doesn't understand to what you're referring.

Here's the line you're missing:

var yearToday = getYear();

This declares a new variable named yearToday. It will call/execute/invoke the function getYear. When we use the return statement we are returning the value to the place where it was called. In this case, the year will be returned to the right side of the equals sign and assigned back into the variable yearToday.

Hope this helps! :sparkles:
