Haven’t seen anything that forbids help topics, so here’s my problem. Any help would be greatly appreciated.  
I’m trying to get the collision to work (for five hours), I started out without the array and someone helped me out and said that arrays were needed for the enemies. So, I put the array in, now there’s a problem with “enemyarray.push(Enemy)” that outputs :

TypeError: Error #1009: Cannot access a property or method of a null object reference.  
at Game\_fla::MainTimeline/spawnEnemy()[Game \_fla.MainTimeline::frame1:27]  
at flash.utils::Timer/\_timerDispatch()  
at flash.utils::Timer/tick()

Many times.  
And many times more.

-When missles and enemies collide, they’re supposed to die.  
-Not actually what happens anymore, broken now.

Attached the file. Thanks to all those who try.
