Did i get it right?

var secondsPerMin = 60;

var minPerHour = 60;

var hoursPerDay = 24;

var daysPerWeek = 7;

var weeksPerYear = 52;

var daysPerYear = 365;

var age = 31;

var secondsPerDay = secondsPerMin * minPerHour * hoursPerDay;

var aliveSeconds = secondsPerDay * daysPerYear * age;

document.write('There are ' + secondsPerDay + ' seconds in a day.');

document.write("<br /> <br />");

document.write('I have been alive for ' + aliveSeconds + ' seconds');

From what I can see, you only have one error. You are missing a ";" after the variable daysPerWeek. However, that won't prevent JavaScript from processing your code.

What exactly is the problem you are experiencing with this code?

Your calculations are correct but you can perform it shorter.

var secondsPerMin = 60;
var minPerHour = 60;
var hoursPerDay = 24;
var daysPerWeek = 7;
var weeksPerYear = 52;
var daysPerYear = 365;
var age = 31;

var secondsPerDay = secondsPerMin * minPerHour * hoursPerDay;
var aliveSeconds = secondsPerMin * minPerHour * hoursPerDay * daysPerWeek * weeksPerYear * daysPerYear * age;

document.write('There are ' + secondsPerDay + ' seconds in a day. <br /> <br /> ');

document.write('I have been alive for ' + aliveSeconds + ' seconds');
