Hi.

It wants you to call the function random_age by giving it an in parameter. You give it an in parameter like this:

function random_age(age) {
  Math.floor(Math.random() *age);
}function // You shouldnt have function after a function. Remove this part.

// Here you need to give a number as an in parameter to the function random_age(), like this:
random_age(A NUMBER);

So in total it should look something like this:

function random_age(age) {
  Math.floor(Math.random() *age);
}

random_age(15);

Try it yourself! I hope this helps :)
