Recived a syntax error and I'm not sure why

Don't know what I'm missing from theses statements.

script.js
var correctGuess = false 
var randomNumber = Math.floor(Math.random() * 10)+1
var guess = prompt("What is the number I am thinking of? It's between 1 and 10")
if (parseInt(guess) === randomNumber {
  correctGuess = true;
}
if (correctGuees) {
  alert('This is true');  
} else {
    alert('This is false');
}

Hi

First of all, you need to end all lines in the beginning with a semicolon, as well as you are missing a end parenthesis in the first if statment.

This would solve your problem:

var correctGuess = false; var randomNumber = Math.floor(Math.random() * 10)+1; var guess = prompt("What is the number I am thinking of? It's between 1 and 10");

if (parseInt(guess) == randomNumber) { correctGuess = true; }

if (correctGuess){ alert('This is true'); }else { alert('This is false'); }

Thanks for the help. I did these corrections and it told me it couldn't find the varaible correctGuess for some reason even though it was defined.

That is because of a typo. You are checking for correctGuees with two e's instead of two s :) I've made that mistake quite a lot!

Anders' solution should work:

var correctGuess = false
var randomNumber = Math.floor(Math.random() * 10) + 1
var guess = prompt("What is the number I am thinking of? It's between 1 and 10")
if (parseInt(guess) === randomNumber) {
    correctGuess = true;
}
if (correctGuess) {
    alert('This is true');
} else {
    alert('This is false');
}

Did any of you guys read the instructions?

This challenge is super simple, It doesn't involve any prompts, number conversion, Math funcitons, random numbers, or program logic.

The instructions say, "Place a Boolean value between the parenthesis for the condition in this conditional statement." So all you need to do is place one single word between the parentheses of the provided code to pass the challenge.

And if you don't put in the right word the first time, it will even give you a hint telling you what to use!
