In order to fault find, I have used a digital multimeter.  Some of the digits on the display are not working. I used the multimeter to locate where there was a break in the protocircuit; this was stopping the voltage getting to one digit on the display. I also had some resistors with both legs on the same copper track on the protocircuit; this resulted in the resistor being bypassed and having no effect.
