Particle fields?

sorry, it just baffles me. How can I make the (force?) field works? Vortex, spherical, etc. I’m trying to animate non-static particles and I can’t get them to work! I have a plane as the emiter and an empty with a vortex field. I’ve tried with force values from the moderately small to the ludicrously strong, and the motion is always the same.

help?

Make sure your force field object and particle emitter are on the same layer.

make sure that your force is going towards the particles. the wing follows the z axis of the empty.

twas the layer thing. Thanks a lot!
