Remove the green osciloscope trace across the zenner diode, then just have one trace on a wire at the LED and see its voltage reading. Start asking if all diodes are facing the correct way. If you get it all working nicely then look in to RMS as a further feature.

Notice the transformer. See here for help: http://everycircuit.com/circuit/5970376018886656 and keep trying.....good luck.
