OK I try my best to explain this. I have this movieclip (instance name “t1”) i use as a trigger when a car (i\_car) hits it. Inside it there is 2 frames. The idea is to get the car going under the bridge when trigged and normally the state is that the car goes above the bridge.

**Frame 1:**  
if (\_root.t2.hitTest(\_root.i\_car)) {  
\_root.i\_bridge.swapDepths(200);  
\_root.t2.\_yscale = 300;  
\_root.track.i\_collision.gotoAndStop(3);  
} else {  
\_root.i\_car.swapDepths(200);  
\_root.t2.\_yscale = 100;  
\_root.track.i\_collision.gotoAndStop(2);  
}  
**Frame 2:**  
gotoAndPlay(1);

I use this trigger at the end of the bridge. (the road going under it). Problem is when ever i put another similiar trigger movieclip, this new trigger doesn’t work. I just can’t find the reason why it wont work.  
This first trigger works fine.

Ok i solved the problem and here’s the solution if someone is interested.

**I added this script to the first trigger movieclip:**  
onClipEvent (enterFrame) {  
if (this.hitTest(\_root.i\_car)) {  
\_root.i\_bridge.swapDepths(100);  
this.\_yscale = 300;  
\_root.track.i\_collision.gotoAndStop(3);  
} else {  
if (\_root.t2.hitTest(\_root.i\_car)) {  
\_root.i\_bridge.swapDepths(100);  
\_root.t2.\_yscale = 300;  
\_root.track.i\_collision.gotoAndStop(3);  
} else {  
\_root.i\_car.swapDepths(100);  
this.\_yscale = 100;  
\_root.t2.\_yscale = 100;  
\_root.track.i\_collision.gotoAndStop(2);  
}  
}  
}  
----------------------- end -----------------

Now there is another trigger movieclip too (t2) and it works. Both of them:)
