jquery waypoints problem

jquery waypoints problem

I'm having trouble with the jquery waypoints plugin:  http://imakewebthings.com/jquery-waypoints/


Whenever I attempt to use this in internet explorer I get an error for my code that only occurs in the IE browser:
Line: 65
Error: Object doesn't support property or method 'waypoint'


Here is the code:
  2. $('#one')
  3. .waypoint(function(direction) {
  4. if (direction === 'down') {
  5. $('a').removeClass("active");
  6. $('#home').addClass("active");
  7. $('.fivedown, .fourdown, .threedown, .twodown').css('display', 'none');
  8. }
  9. }, { offset: 1 })
  10. .waypoint(function(direction) {
  11. if (direction === 'up') {
  12. $('a').removeClass("active");
  13. $('#home').addClass("active");
  14. $('.fivedown, .fourdown, .threedown, .twodown').css('display', 'none');
  15. }
  16. }, { offset: -1 });



Edit: I'm not positive, but I think it has something to do with the function(direction) part.
