I’m trying to remove an element from electrical circuit using the RemoveFromCircuit method and I’m getting the error - “RemoveFromCircuit() takes exactly 2 arguments (1 given)”  
the argument should be an elementset of the components. What is the second argument?  
Is there another method to remove an element from an electrical circuit?

I was looking at my files again today with fresh eyes and it’s working 🙂
