How can I get my codes to run?

function getRandomNumber( upper ){ var randomNumber = Math.floor( Math.round() * upper ) + 1; return randomNumber; } console.log( getRandomNumber(10) );

When I run the code from my workspace unto the browser, I then check the JavaScript console only to see error "NaN" on random.js: 5 i.e the console.log line

It looks like you never called Math.random(), instead you have Math.round() which your Math.floor() is already taking care of.

function getRandomNumber( upper ){ 
var randomNumber = Math.floor( Math.random() * upper ) + 1; 
return randomNumber; 
} 
console.log( getRandomNumber(10) );
