Code Challenge: The Math Object Task 4

I can not figure out what I am doing wrong.

"There is a variable "ageIfILiveToYear2100" already defined but it has a lot of decimal places. Create a variable named "age" and use the Math.floor method to lop off the decimal digits." 

      var diameter = 5.75,
          a = 17,
          b = 42,
          c = 1337,
          ageIfILiveToYear2100 = (new Date(2100, 0, 1) - new Date(1995, 5, 16, 7, 20)) / (1000 * 60 * 60 * 24 * 365.242);
            circumference = diameter * Math.PI;
            chance = Math.random() * 20;
            maxWidth = Math.max(a, b, c);
            age = Math.floor(ageIfLiveToYear2100);

Look at what variable you are passing to floor.

Hi. Yes Sean's comment is the correct answer. Copying and pasting long variable names helps avoid typos.

var circumference = Math.PI*diameter; var chance = Math.random()*20; var maxWidth = Math.max(a, b, c); var age = Math.floor(ageIfILiveToYear2100);

eye was stuck too....
