Here you have assigned the Console.WriteLine() method to the variable firstName. The exercise wants you to use Console.WriteLine() to print the value stored within firstName to the screen.

string firstName = Console.ReadLine();
Console.WriteLine(firstName);

as you can see in the code above, you assigned the string that the user inputs into the variable first name. Then the that string is printed to the screen within the Console.WriteLine().

Hope this helps

The ReadLine function returns something back, that's what you are using in your assignment.

But the WriteLine function needs you to give something to it. When you pass parameters to a function, they must be inside the parentheses (). And you won't want to assign anything using it.

Also, you have two extra lines that both declare and assign a variable named entry. That's not part of the challenge and you don't need either of them; and since you can only declare a variable once, the second one will cause a compiler error.
