How do i solve Bmmer Did you forget to pass the `lastName` parameter to the printf function?

I am a bit lost as to what i am doing wrong in this code challenge.

IO.java 
// I have imported java.io.Console for you.  It is a variable called console.
String firstName = console.readLine ("first name  ");
String lastName = console.readLine ("last name  ");
console.printf("%s", firstName);
console.printf("First Name");
console.printf("%s", lastName);
console.printf("Last name", lastName);

Using the console's printf method, display a message that says, "Last name: " followed by the last name that the user has entered. This is the question the code challenge is asking me to do. I am lost at this point and trying to see my error

I'll give you a hint on how to do first name in the way that the challenge is asking you to, hope this helps.

String firstName = console.readLine();
String lastName = console.readLine();
console.printf("First Name: %s", firstName);
