Button Navigation

Hi,

I’m working in MX 2004 Pro and building a movie with slides. When I click a button to load the corresponding slide, it starts at frame 1 and plays the motion-tween animation; just what I want. However, when I leave this slide and come back to it, it loads at the end of the motion tween. In effect, the animation only plays once! How do I script the button to go to a slide AND force it to go to the FIRST frame every time that screen is loaded?

Thanks folks

J
