I need to animate a scroll from the current screen position up or down, when the scrollbar move up or down.

I'm using this script, but doesn't work ok:

var iScrollPos = 0;
 $(window).scroll(function () {
 var iCurScrollPos = $(this).scrollTop();
 if (iCurScrollPos > iScrollPos) {
 $('html,body').animate({
 scrollTop: $(window).scrollTop() + 100
 })
 } else {
 $('html,body').animate({
 scrollTop: $(window).scrollTop() - 100
 })
 }
 iScrollPos = iCurScrollPos;
});

The problem is that a loop appear on the scroll down.
