:point_right: It looks like you changed a bit more than was asked for.

In the original RepeatDetector.cs, line 16 was "return true;", but you changed it to be "return Description;".

The challenge was just to override the Description property, which you did correctly. The extra change inside the Scan method is not part of the challenge and is causing the check to fail.
