How do I use "Pick by Comparison"?

I've tried using pick by comparison in an id system, but im not able to use the parameters the way I've intended.

Basically, what I am trying to do is make a system in which a spaceship has an id (eg: 0) and any other object with that same id (0) will set things like its target's position to that spaceship's id. The problem is that from what i can tell, the pick by comparison parameters do not reference instances besides the one to be picked as one of the parameters. This means the spaceship is not able to pick other objects with its id meaning the system does not work at all.

If anybody knows if i am doing something wrong, do not need to use pick by comparison or if this is a known bug, PLEASE tell me.

Thank You

You are correct, the pick by comparison does not choose instances. You can use the object conditions for comparison. For example if you are trying to set Object to the Spaceship position you can say Object (compare instance variable), Object.ID=Spaceship.ID, then on actions set Object position to Spaceship.

Thank you for your help, i have been stuck on this for days. In case it might help i will send a screenshot of what the code should end up like if it helps.
