hi,
The diagram is a little unusual, if I am reading it correctly, is that diode upside down.??

yes it is a diode...oh i see i have connected the diode the wrong way round ..is that the only mistake?

I must admit I am having difficulty with the way the circuit is drawn....

when i simulate it ..this is the error i get [At time 4.285525085934517e-005, simulation hits (1000) consecutive zero crossings. Consecutive zero crossings will slow down the simulation or cause the simulation to hang. To continue the simulation, you may.. Try using Adaptive zero-crossing detection algorithm

What does the symbol on the right with the 3 arrows do? I am not familiar with your program.
