codes not working!

Hello

Here is my codes thats not working ( I can see only the title of the page not any javascript message !)

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

var attempts= 0; function getRandomNumber(upper) { return Math.floor( Math.random() * upper ) + 1; }

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

document.write("<p>The random number was " + randomNumber + "</p>"); document.write("<p>It took the computer " + attempts + " attempts to get it right."</p>");

Your while loop is not actually comparing anything.

while( !== randomNumber)

You have to have a conditional statement like 

while (guess !== randomNumber)

document.write("<p>It took the computer " + attempts + " attempts to get it right.</p>");

There is an extra quote mark right at the end of the sentence before the </p> tag. Shown here I have removed it. I checked from their and it works.
