i don't understand where i'm going wrong

the question giving an age and when i put the parameter (age) it does't recognize it. or if age should logically be a number

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

The problem probably is that "age" is undefined. Make sure you're passing a number as an argument.

var age = 21;
random_age(age); // age is now defined.

Or maybe I'm not interpreting your question correctly.

you mean like this off of the sample ? // Get a random number between 0 and a passed-in number
