Constrain to a curve

[dane]

Is it possible to constrain a Locator to a curve? I know you can use the geometry constraint to lock a locator to a surface but I want to do the same thing to a curve. The path animation tool comes close, only I don't want the locator to move over time I want it to be able to be easily animated going back and forth.

The geometry constraint will work with curves.

Thanks. The reason I couldn't get this to work before was that the constraints wouldn't duplicate, so I went and tried the path anim stuff with no success. But thanks to your post I discovered the duplicate inputs option and should now be able to get things going.

Alas, this kind of animation has no Uvalue which makes it kind of a pain to set attributes for in MEL.
