This is the correct answer

var firstName = 'Will';
lastName = 'Jones';
fullName = firstName + lastName;

So you have

var firstName = "will"; 
var lastName = "jones"; 
var fullName = (firstName ' ' + lastName); 
document.write (fullName);

The problem is in the var fullname line. You want:

var fullName = firstName + ' ' + lastName; 

You missed off the first + sign after firstName.

Random Challenge:

var userInput = prompt("Enter any number"); var convertInputtoInt = parseInt(userInput);

var dicRoll = Math.floor(Math.random() * convertInputtoInt) + 1; alert("you generated this number " + dicRoll);

Code should like this:

var firstName = "will"; var lastName = "jones"; var fullName = ("firstName + lastName")

I'm struggling to find my own errors: https://w.trhou.se/gw6tmbsu5d

var firstName = "Mary"; var lastName = "Jones"; var fullName = firstName + lastName; document.write(fullName);

Yeah I had a problem with that the fix is that the fourth line that has var fullName = ("firstName + lastName"). I would have though you would not have used "" as they are variable not strings. However, we are outputting strings from the variables I think thats the reason.

This is easy and can be answered different ways. You just have to combine the first variable with the last variable using +.

var firstName = "John";
var lastName = "Doe";
var lastName = firstName + lastName;
