Problem with spawning engine

[flytex]

For problem solvers!
Hello, this is a problem involving spawning objects.
The code below creates this.
http://www.swfcabin.com/open/1304522916
To "play" simply left click once

Before spawning an atom the current code makes sure that an object wont collide with any existing objects, just as I want it to be. However once a subatom has been spawned the coming atoms wont spawn at any of the three remaining binding points "left bottom top or right". (as it should)

The only error message appearing (occasionally): a term is undefined and has no properties at atom_fla::MainTimeline/doAll()

This problem is caused by the code checking the collisions of coming objects.

Removing this code makes this:
http://www.swfcabin.com/open/1304522783

if you wait for a bit you'll see that the objects spawn onto each other.

while(checkTal<spawnLista.length){
						if(spawnLista[checkTal].name!=spot[0][0].name){ 
							if(spawnAtom.hitTestObject(spawnLista[checkTal])){
							
							  reDo=true;
							}
						}
						checkTal++;
					}
					if(!reDo){

Bottomline, I need this code to make the game playable, suggestions of different solutions or other changes to simply make it better are highly appreciated!
