Hi there! A member variable (or field) is simply a variable that belongs to that class. You create it just like you would any other. In this case, it wants a public string.

public String title;

This creates a field/member variable that belongs to this class. It is public, of type String and has the name title.

Hope this helps! :sparkles:
