Auto scrolling thumbnails direction...?

1

I found the code for the auto scrolling thumbs and works fine but is there a way to make scroll in the opposite direction?
Thanks a lot
code;
tscroller.onEnterFrame = function() {
if ((_root._ymouse>=thumbnail_mc._y) && (_root._ymouse<=thumbnail_mc._y+thumbnail_mc._height)) {
if (_root._xmouse>=(hit_right._x-40)) {
for (var obj in cliparray) {
cliparray[obj]._x -= scroll_speed;
}
if (cliparray[0]._x<-cliparray[0]._width) {
cliparray[0]._x = cliparray[cliparray.length-1]._x+cliparray[cliparray.length-1]._width+5;
var j = cliparray.splice(0, 1);
cliparray = cliparray.concat(j);
}
} else if (_root._xmouse<=(hit_left._x+40)) {
for (var obj in cliparray) {
cliparray[obj]._x += scroll_speed;
}
if (cliparray[cliparray.length-1]._x>hit_right._x) {
cliparray[cliparray.length-1]._x = cliparray[0]._x-(cliparray[cliparray.length-1]._width+5);
var j = cliparray.splice(cliparray.length-1, 1);
cliparray = j.concat(cliparray);
}
}
} else {
for (var obj in cliparray) {
cliparray[obj]._x += scroll_speed;
}
if (cliparray[cliparray.length-1]._x>hit_right._x) {
cliparray[cliparray.length-1]._x = cliparray[0]._x-(cliparray[cliparray.length-1]._width+5);
var j = cliparray.splice(cliparray.length-1, 1);
cliparray = j.concat(cliparray);
}
}
};
