Thankgod firebug exists.
Enter numbers for their birthdays without 0's preceding such as
1 2 3 4 5 6 7 8 9 10 11 12 13 14 etc
You also stripped out too many {} brackets. Trying to find where you're missing one...
Edit:
Find this:
Code:
$(document).ready(function(){
calage();
});
On the line
before it, add a }
