Im trying to make a game 4 my dad but it doesn't work as i want it to. grr

Its supposed to go back to the beginning when you crash into a asteroid but it doesnt
heres what ive done w/ the code

Code:
Asteroid 

onClipEvent (enterFrame) { if (this.hitTest(_root.player_mc)) {  this._alpha = 50;  
crash = "true"; } }




frame 2

if (crash = true) {
gotoAndStop(1);
}
I dont know how to monitor true/false so i dont know if it is setting the variable. But i kno that the asteroid has been hit because it fades out...
Please
