Radius Search Failing?

I have created a function that will allow a bot who is being attack to yell for help, and if any bots are within a specific radius, they will come and jump in on the action.

Here is the relevant bits of code.

function DoRadiusSearch(%client,%distance,%searchMasks,%AI){
   if(%AI){
   	%player = %client;
   }else{
   	%player = %client.player;
   }
   %pos = %player.getPosition();
   InitContainerRadiusSearch(%pos, %radius, %searchMasks);
  
   while ((%targetObject = containerSearchNext()) != 0) {
	%dist = containerSearchCurrRadiusDist();
	%target = %targetObject.getTransform();
	%id = %targetObject.getId();
	%name = %targetObject.getName();
	
	echo( "\c3 /// Container Search /// " );
	echo( " Distans = " @ %dist);
	echo( " Player Position = " @ %pos);
	echo( " Target = " SPC %target);
	echo( " Target Id = " SPC %id);
	echo( " Target Name = " SPC %name);
	echo( "\c3 /// --------------- /// " );
	%radiusObjectVector = %radiusObjectVector SPC %targetObject;
   }
   if(%radiusObjectVector){
		return(%radiusObjectVector);
   	}else{
		return(0);
   }
}

//This function allows a shout for help to be made which will call the closest NPC within a given radius to help.
function ShoutForHelp(%client,%targetObject,%radius){
	%searchMasks = $TypeMasks::PlayerObjectType;
	%AI = 1;
	%radiusObjectVector =  DoRadiusSearch(%client,%radius,%searchMasks,%AI);
	while (getWord(%radiusObjectVector, %i) !$= "")
	{
		%helper = getWord(%radiusObjectVector, %i);
		if(%help !$= 0)
		if(%helper.getClassName() $="AIPlayer"){
			%helper.setSelectedObject(%targetObject);
			echo(%helper.getShapeName()@" is on the way to help");
			schedule(500,%targetObject,ServerCmdAutoAttack,%helper);
		}
		%i ++;
	}
}

Near as I can tell there is no reason for the code above to fail unless there are no PlayerObjectType objects within the specified radius... But I'm getting failures even with a radius of 5000. I have 20 bots each is spawning in a standard playerspawn location in stronghold. Theoretically, when I attack any one bot, every bot in a 5000 unit radius should come running, but they don't instead I keep seeing this in my console.log

Quote:
Entering ShoutForHelp(1144, 1141, 5000)

Leaving DoRadiusSearch() - return 0
Dream.game/server/scripts/commands.cs (505): Unable to find object: '0' attempting to call function 'getClassName'

This is driving me batty, it looks like it may be a typemask problem, but if it is then I don't know what else to use.
Here is my AI creation function

// Start the AIManager
   new ScriptObject(AIManager) {};
   MissionCleanup.add(AIManager);
   //AIManager.think();
   for(%x=0; %x <=10; %x++){
        schedule(1000 * (%x * 10),0,"MakeAI");
   }


function MakeAI(){
   $x++;
   %aiPlayer = AIPlayer::Spawn(%x,pickspawnpoint(),"aiOrc");
   //%aiPlayer.maxInv[Sword] = 1;
   %aiPlayer.setInventory(Sword,1);
   //%aiplayer.setInventory(CrossbowAmmo,10);
   %aiPlayer.mountImage(SwordImage,0);
}

Well any help would be appreciated, thanx!
