JavaScript JavaScript Basics (Retired) Working With Numbers The Random Challenge

I'm unsure what I'm doing wrong. It's working fine when I preview it until I get to 'math.random()' part

console.log("Begin program");
alert("Welcome! Are you lucky enough?");
var questionOne = prompt("Please enter your first number below.");
var integerOne = parseInt(questionOne);
var questionTwo = prompt("Please enter your second number below.");
var integerTwo = parseInt(questionTwo);
var message = math.random()* (integerTwo - integerOne + 1) + integerOne;
document.write("Here" + "'s" + " your lucky number" + ": " + "message" + ".");
console.log("End program");

:point_right: JavaScript is case-sensitive. You want Math, not math.

Also, if you want to display the random calculation instead of the word "message" itself, you'll need to remove the quotes from around message in your document.write.

And you might want to make use of Math.floor() to use only the integer part of that calculation.

document.write("Here" + "'s" + " your lucky number" + ": " + "message" + ".");

You are typing the variable message as a string, no as a variable, delete the quotation marks so it will work as a variable.

document.write("Here" + "'s" + " your lucky number" + ": " + message + ".");

Here's a rewrite of some of your code that worked for me.

console.log("Begin program"); alert("Welcome! Are you lucky enough?"); var questionOne = prompt("Please enter your first number below."); var integerOne = parseInt(questionOne); var questionTwo = prompt("Please enter your second number below."); var integerTwo = parseInt(questionTwo); var message = Math.random() * (integerTwo - integerOne) + integerOne; var message = parseInt(message); document.write("Here" + "'s" + " your lucky number" + ": " + message + "."); console.log("End program");
