Make the slider go right

Hello guys

I have mad this from a tutorial. Now the slider goes left but i wants it to go right but i just cant seem to get it to work.

Here is the code

onClipEvent(load) {
 
 looping.duplicateMovieClip("logo_slide");
 logo_slide._x=looping._x+looping._width+16;
 loopStartx = this._x
 loopSpeed=5;
 
 loopx=_root.slide_mc.looping._width/3;
 loopStart=true;
}
onClipEvent(enterFrame) {
  this._x-=loopSpeed;
  if(this._x<=(loopStartx-looping._width)){
   this._x=loopStartx-loopSpeed;
  }
 }

I have tried to gange this

this._x-=loopSpeed;

to this

this._x+=loopSpeed;

But that dont work. Can anyone help?
