Smart Table Track SketchUp component

I just uploaded a Dynamic Component for the new version of SketchUp
(7). It is the Smart Table Track with wood installed, and the slider can be extended
any amount you want just by typing in the amount desired in the
component attributes window. I highly recommend that you try version 7 of
SketchUp, it is faster, more stable, and the availability of Dynamic
Components is going to open up all kinds of possibilities.

Note: Peter West pointed out that I still have some work to do with the
component, I'll post again once I have fixed the problems.

Note: New version uploaded. Hopefully this one works properly. Let me know if there are problems.
