I’m using the thumbnail gallery tutorial from this site, and I was wondering how I could add deceleration to the horizontal scroller. Here is the scroller part of the code from the flash file:

```php
function thumbNailScroller() {
// thumbnail code! 
this.createEmptyMovieClip("tscroller", 1000);
scroll_speed = 40;
tscroller.onEnterFrame = function() {
if ((_root._ymouse>=thumbnail_mc._y) && (_root._ymouse<=thumbnail_mc._y+thumbnail_mc._height)) {
if ((_root._xmouse>=(hit_right._x-40)) && (thumbnail_mc.hitTest(hit_right))) {
thumbnail_mc._x -= scroll_speed;
} else if ((_root._xmouse<=(hit_left._x+40)) && (thumbnail_mc.hitTest(hit_left))) {
thumbnail_mc._x += scroll_speed;
}
} else {
delete tscroller.onEnterFrame;
}
};
}

```
