Hi, as you can see here:

a little ant like bicycles ride below the header, how can i make this to be an infinite loop and not begin all over when the layer ends?

this is the original .fla file:

btw, you are all invited jejeje

Have the animation complete and use

gotoAndPlay(2);

In the actionscript at the last frame to have it go to frame number 2 (or whatever you want) and continue to play.
