How do you make particle Objects to follow path alignment?

I am working on a project where I need arrows to flow inside a pipe. I have set up a path and applied a force field to it with a particle emitter.
The particle emitter uses a 3D arrow for the object.
I want to make the arrow follow the alignment of the path. Currently it won’t change directions as it flows along the path. Just points in the same direction.
If I click the Rotation Check Box in the Particles area, it randomly spins the arrows.

If I click the rotation button under the Render, it points in the same direction.

Any suggestions?

If you select the Rotation panel and then select Dynamic it should work.

Thanks. I just put up a new post. For the most part, most of them follow the path but some bounce around. I am not sure if I have set up my object correctly.
