_level problem

Hi,
I have a exported mc with an instance name of Car_3d_container and i attach the clip and load it to level1. now i want to refer to its timeline, my understanding is that it would be somthing like _level1.Car_3d_container.gotoAndPlay(2); but its not working.

Can anyone help?

Thank you in advance

PS here is how im attaching the clip

this.attachMovie("Car_3d_container","Car_3d_container",1());
