Hi this is my code as I tried copying it from the example. however the prompt box comes up then nothing happens. what is wrong with it? thank you

var input=prompt('please type a number');
var topnumber= ParseInt(input);
var randomnumber= Math.floor(Math.random()*topnumber) +1;
var message ='<p>'+randomnumber+'is a number between 1 and'+topnumber+ '</p>';
document.write(message);

Hi Daniel,

It looks like you're almost there you just need to use the parseInt method properly, with is in camelCase with a lowercase p. Try the following it should work properly. :)

var input=prompt('please type a number');
var topnumber= parseInt(input);
var randomnumber= Math.floor(Math.random()*topnumber) +1;
var message ='<p>'+randomnumber+'is a number between 1 and'+topnumber+ '</p>';
document.write(message);

By the way I changed your original post to show it in JavaScript format. Checkout the markdown cheatsheet link below for tips on how to add code to your posts :)
