D'oh! Ignore the above suggestion... or at least reset it to all zeros before you enter that loop below there - I was just trying to account for points not connected to ANY polygons, but you should probably handle that error condition differently anyway.
@Matthias - thanks for the corrections/additions... I'd forgotten about th normalization, so that extra divide at the end of the loop is not needed.
