Answer not defined?

Hi there, when I run this code in Chrome I receive the error message "answer not defined:"

prompt("Who is the only person Voldemort feared?"); if (answer.toUpperCase === "DUMBLEDORE") { document.write("<p>Nailed it.</p>"); }

What's the deal?

have you defined the variable somewhere in the document? try,

// Put the prompt in a variable
var answer = prompt("Who is the only person Voldemort feared?");
// Make the variable string uppercase (nicer this way)
answer = answer.toUpperCase();
// Console log the answer for dubugging
console.log(answer);
// Create the argument, remember that answer is already capitalised now
if (answer === "DUMBLEDORE") { 
    alert("You said " + answer + " you nailed it.");
} else {
    alert('You are wrong! you suck!');
}

Hope this helps.

I got it! Forgot to assign the prompt to the variable answer.
