Wha's wrong with this ODE code?

Hi mates!
I'm trying ODE for first time and something does not work. I guess this is a falling ball, but I see the same Y value through the time.
Do you see anything strange?
Thanks in advance.
I'm no ODE expert, but it seems you are settings gravity to be on the Z axis
dWorldSetGravity(world_id, 0,0,-9.81);
and then move the body on the Y axis
dBodySetPosition(body_id, 0, 10, 0);
So naturally, Y wont change.
dWorldSetGravity(world_id, 0,0,-9.81);
and then move the body on the Y axis
dBodySetPosition(body_id, 0, 10, 0);
So naturally, Y wont change.

You were right, thanks a lot ;)
