Here's what I want to do. I have a logo.......and I want it to fade away when the user rolls over it and then fade back to it's original state when the user rolls out.

So i have a movie clip with the motion tweening and the images....and it works well on it's own timeline.

But then I try to put it in the main timeline and that's when the confusion begins. True or false...i need to create a seperate button....and give it actions to control the clip? This is confusing to me......So what I did was to create a button that was the same as the logo....and I gave it the tell target commands that would send it to the fade out part of the movie clip on roll over and send it to the fading back part of the movie clip on roll out. However...when it fades out....it doesn't,,,,because the button is still there. Also, where must the movie clip be? On the stage? Transparent? I am obviously confused about the basics and am looking for some help.

Also, if you could address my problem specifically and not send me to some watered down tutorial that brushes through the basics, i'd appreciate it.
Thanks
