Flash MX Alpha tween

I apologise if this has already been posted. But I am wondering how do you perform a simple alpha tween in flash mx ?

I remember in flash 5 you could simply go to the effects tab and chose the alpha percentage for both key frames, then create a motion tween and voila !

However I am having no such luck with flash mx

any suggestions would be greatly appreciated

use the properties thing at the bottom. like after u have ur tween done, click on ur mc then it will let u in the properties thing.
