David Mulholland — Glad to help. But normally you'd mark "best answer" on the one that contained the information that helped most!   :see_no_evil:

(You can still change it :wink:)

The assigment operator is a single character "=". When you use two of them ("=="), it is a comparison operator.

//    else { this._major == 'None';   // original code
      else { this._major = 'None';    // fixed
