Complex Rollover Tutorial Issues

I am following tutorial: http://www.kirupa.com/developer/mx2004/button_effect.htm

And everything works perrfect, just the way it should.

Now…

I converted the MC to a BUTTON and I’m using the buttons to do the transitions for this tutorial:

When I do, the buttons simply does not work. I click on the buttons and nothing happens. I take the actionscript out for the rollover effect and it works fine again.
Oh when I say nothing happens, I mean the transition between the external SWF does not work.

Any ideas?

Thanks in advance.

Andre.
