Can someone tell me what's wrong with my code? It's just not working. 

var randomNumber = Math.floor(Math.random() * 6) + 1;
var guess = prompt( "I am thinking of a number between 1 and 6. What number am I thinking of?");
if (parseInt(guess) === randomNumber) {
  document.write("<p> You guessed it!</p>");
} 
 else {
  document.write("<p>The correct number was" + randomNumber "</p>"); 
}

Hi there! In short: you forgot a + sign. This is creating a syntax error in your code. If I rewrite your last document.write statement, it works! Take a look:

document.write("<p>The correct number was " + randomNumber + "</p>");

Note that I also included an extra space in the string. Otherwise the output looks like this: "The correct number was2". Hope this helps! :sparkles:

I was using JShint.com to test my code and it kept throwing errors for line 7.

Expected ')' and instead saw ' '. 7 Missing semicolon. 7 Expected an identifier and instead saw ')'. 7 Expected an assignment or function call and instead saw an expression.

and it was in fact the second addition symbol that I was missing ... I REALLY HATE JS, and yet its fascinating enough to keep trying.
