Well Ron, please excuse me for being thick I think it may have finally sank in, at least I hope so.
I breadboarded the thing again, and got the result that worked, I didn't need the Transistor on the output. So I put it back into the circuit board, with the necessary adjustments, guess what no output again, then I woke up, the board is setup for 5 sensors, of which I had only connected, so according to the truth table with these all sitting on high the output would read high, by switching on the one single sensor, it would still read high, I would need all the sensors connected and switched on to get a low. the reason it worked on the breadboard, I had only the one set of pins connected. hope my logic is correct here.
