Can't get my javascript to show up in my html file when I view it.

Can anyone help show me where I'm going wrong. I've ran it with a few different ways and still nothing. Frustrating as you can imagine.

Thanks :)

Here's my code:

var upper = 10000; var randomNumber = getRandomNumber(upper); var = guess; var = attempts;

function getRandomNumber(upper) { return Math.floor( Math.random() * upper ) + 1; }

while (guess !== randomNumber) { guess = getRandomNumber(upper); attempts += 1; }

document.write("<p>The random number was " + randomNumber + "</p>") document.write("<p>It took " + attempts + " to guess right</p>")

Hey Niall,

When you're making new variables, you only need to put var attempts instead of var = attempts and the same for the guess variable. Just remove the equals from the very top where you create the variables. But, for attempts, since you are adding 1 to it, I would create it as var attempts = 0; so that there is a starting point for attempts.

Also, in your first document.write(), you can put a period and a space in the empty string so that it looks nice on the page and you should put semi-colons on the end of your commands:

var upper = 10000; 
var randomNumber = getRandomNumber(upper); 
var guess; 
var attempts = 0;

function getRandomNumber(upper) { 
return Math.floor( Math.random() * upper ) + 1; 
}

while (guess !== randomNumber) { 
guess = getRandomNumber(upper); 
attempts += 1; 
}

document.write("The random number was " + randomNumber + ". "); 
document.write("It took " + attempts + " to guess right");
