gives me the error: nested iteration detected.

What does this error mean and how do I fix this?

You are using a " Unit Group - Pick each unit in (...)" inside of another " Unit Group - Pick each unit in (...)". That does not work, and it doesnt make sense either.

You can only have one group itterator at a time as it binds to the current thread for speed instead of using an object.
