Can anyone identify why the error message isn't showing up? 

function getRandomNumber( lower, upper) {
  if ( isNaN(lower) || isNaN(upper) ) {
  throw new Error('You did not enter a numerical value');
  }
  return Math.floor(Math.random()*(upper - lower +1)) + lower;
} 
console.log( getRandomNumber(3, adfg) );

Hi Jonathan,

The second argument you are passing to the function is interpreted as a variable. This is why you get an uncaught ReferenceError: adfg is not defined.

If pass it a string like this, your code will work:

console.log( getRandomNumber(3, 'adfg') );
