Plane doesn't know were the way points are

Hi Guys new to the APM plane and have every thing talking to the plane can change speed in flight but it will not loiter, circle, RTL or fly a mission it seems as though it dose not know were it is, I have heard something about pids? can anyone help.

I have done GPS live calibration and have low values before this I had high values and it was the magnets that hold the hatch on.

Thanks
