function random_age(age) {
// Creating the function random_age and passing the age variable as a parameter
  Math.floor(Math.random() * age)
// Rounding down a random number then timesing by 70 which was passed into the function when i called random_age
}
random_age(70);

The "age" variable declared on the top line isn't being used in this code (and is not needed). The only thing needed for this challenge is to plug in a value for the parameter.

You are correct Steven thanks for pointing that out! I tunnel visioned and placed it there trying to translate his code over!

It looks like you have called the function correctly on the bottom line. But you also modified the function itself which created the issue. Remove that modification, or start over and leave the provided function as-is.
