spawned artillery logic, and synchronization with dynamic objects help

ok so I have a question about what the topic is about. I've tried using the method in the wiki for spawning the module, the problem is that I am using the dynamic objects compositions for US1_FireBase, and the M119s are empty, however I have a couple preplaced group which call BIS_fnc_taskDefend within the radius of the composition. When I try to debug it using count synchronizedObjects _battery, it returns zero even if I use waitUntil {!isNull gunner _x} for an array that uses [_obj,["M119"],1000]. I don't know if its a problem using dynamic objects or not.

help?
