Animate on action one way to the next issue.

Hello,

I have been working with this for sometime and have all the buttons and path shapes working without errors. I just cant seem to figure out how to make the animateMotion to react correctly. What I am trying to do is move my button set down the path on a button_down action and then back when when I select the button_up. This is my first post so I do appologize if this seems like tomuch of a newb question.

</animateMotion>
<animateMotion id="Button_Path_Down"dur="0.5s" begin="buttons.activate" rotate="auto" fill="freeze">
<mpath xlink:href="Path_2"/>
</animateMotion>

<set xlink:href="#Button_Go_Down" attributeName="display" to="none" begin="Button_Path_Up.activate"/>

I'm learning and see to zillion ways to do this. Im thinking about defining the buttons in the <defs></defs> and calling it up by the <use> Still having trouble with the controls though. But would this help for structure and I guess I should know if it cant be done? I was also thinking to try and use <markers> for the <path> instead of having two <path>'s.
