you are getting the error to the pad in coordinate x=2, y=3 because you cannot connect to another pad. If you look at the documentation you can find the connectivity options for every element. Why would you couple three pads together? Move forward the two pads around the nucleation center and your issue will be solved.
Remember also to assign an output pin to the circuit.
