Animate an element to move between 2 elements in a dynamically created curved path

Question

I've been trying to do this for a project and i failed on every try. The image says it all. The idea is to create a script to: Select Start Point and Ending Point elements. Move "bee" between this 2 elements in a certain time when the function is called.

I can't post images :/ here's the link http://i59.tinypic.com/swakav.png
