Welcome to my onEnterFrame nightmare.

OK, so I’m doing this tutorial, which is pretty straightforward, and I’ve got it to work so far. Here’s what it looks like:

on the main timeline:

stop();  
\_root.slidingObject\_mc.onEnterFrame = function() {  
if (\_root.running && Math.abs(\_root.marker\_mc.\_x-this.\_x)\<1) {  
this.\_x = \_root.marker\_mc.\_x;  
\_root.running = false;  
} else if (\_root.running) {  
this.\_x -= (this.\_x-\_root.marker\_mc.\_x)\*.5;  
} else {   
}  
};

on the buttons:  
on (press) {  
\_root.marker\_mc.\_x = 55;  
\_root.running = true;  
}

Here’s what I want to do and I’ve tried to write it a BILLION times and failed -

While running = true, I’d like the timeline of slidingObject\_mc to play.

While running = false, it should stop.

HOW DO I SAY THIS IN AS?!! It’s driving me totally NUTS! and, more importantly, once I’ve said it, where to I put it?! On the movie clip I want to play? On the main timeline? Argh!

Please help, I’m sure it’s a very simple question…

Thanks.
