Infinite menu


I am trying to work out something with this tutorial:

I have one movieclip (menu) that is made by 6 pictures x 100 pixels = 600 pixels. I have repeated it into menu_general. So as I figure it out it is 1200 pixels as a totall.

This is the code that I have assigned to the menu_general movieclip:

onClipEvent (load)
onClipEvent (enterFrame)
   var distance=_root._xmouse-xcenter;
   if (_x > 0) _x=-1200;
   if (_x < -1200) _x=0;

The result can be viewed here:

It doesn’t work as it should. Can anyone please tell me what I have done wrong here?

I have attached my scroll.fla file if someone feels like taking a look at it.

Would be nice with some help!
