Nothing tricky here, except one thing. Changing the battery voltage and resistances has proven to be not-obvious. In the sim, click on the slider (middle) tab. By default, the magnifying glass is on the battery. You can toggle voltage up or down. Then click on any resistor, and the magnifying glass indicates that now you can change the resistance.
