I’m trying to express my age on my ABOUT page using javascript so I never have to update it. So wrote a JavaScript function.

```auto
 
function MyAge (BirthYear) {
ThisYear = new Date().getFullYear();
YearAge = ThisYear - BirthYear:
document.write("I am "+YearAge+" Years Old");
}

```

It should work. Here are all the dates below and the intended result.

BirthYear = 1982  
ThisYear = 2005  
YearAge = 2005 - 1982  
I am 23 years old…

To me this seems logical. Where am I going wrong?
