Completing the Random Number Challenge Part II - Trouble getting error code to run

I can run the code, up until the error should display. For some reason, the error doesn't display. Any suggestions?

function randomNumber(num1, num2) {
    if ( isNaN(num1) || isNaN(num2) ) {
      throw new Error('Both arguments must be numbers');
    }
    return Math.floor(Math.random() * (num2 - num1 + 1)) + num1;
}

console.log( randomNumber(18, 24) );
console.log( randomNumber(100, 500) );
console.log( randomNumber('ten', 10) );
console.log( randomNumber(15, 37) );

The only way that I could repeat your issue was to disable JavaScript error output in the console. Can you verify that yours is enabled?

?? I tried the code in Chrome, Firefox, and a Workspace and I always get the error displayed in the console as it should. I'm not sure why it wouldn't display for you. Do you get the first two random numbers and then nothing?

Yep, first two numbers, then nothing. I'm also using Firefox.
