moving multiple layers at once

Help!

Just installed the PVII Layout Designer2 extension.

I can't seem to do what I want to do though.

Go to http://207.176.137.246/test.htm and click on the light green
rectangle. The purple moves to the right of it. So far, so good. However
I also want both rectangles to then slide to the left. How do I accomplish
this? I also have the FlevOOware Slide Layer extension installed and
haven't been successful with that either.

Any words of wisdom ???

Thanks,
mickey
