Hi there,

I'm using the Markdown CheatSheet to make your code easier to read:

var myNumber = prompt('write your number');
var top = parseInt(myNumber);
var randomNumber = Math.floor(Math.random()

If you look above, you are missing the closing parenthesis and semicolon for your Math.floor function.

Should be: 

var randomNumber = Math.floor(Math.random());

code is like this var myNumber = prompt('write your number'); var top = parseInt(myNumber); var randomNumber = Math.floor(Math.random() * top) + 1; var message = '<p>' + randomNumber + ' is a number between 1 and ' + top + '. </p>'; document.write(message);

now its not working properly, i am getting result but that's not what i expected

Hi there! For your future responses, if you look below the text input field, you will see a reference to a Markdown Cheatsheet. It mentions there how you can add markdown so your code becomes easily readable.

You have this (I added notes as comments):

var myNumber = prompt('write your number');  // So let's say someone says 10, it'll be 10 as a string, like: "10"
var top = parseInt(myNumber); //This parses: "10" to become 10.
var randomNumber = Math.floor(Math.random() * top) + 1; //This finds a random number between 0 and .9999ff, then times by 10, then finds the floor (0-9), then adds 1, so 1-10.
var message = '<p>' + randomNumber + ' is a number between 1 and ' + top + '. </p>'; document.write(message);

Which part is confusing for you?
