I am trying to create a flash animation in which a text title fades in to the screen. I created the text, converted it to a symbol, then tried to create a motion tween in which I could tweak the alpha values of the text object. However when I try to create the keyframe, the popup that comes up has the Color option greyed out (which is where I believe the alpha setting lives).
Any idea where I'm going wrong?
You say you are trying to tweak the text object's alpha. If you are tweening the symbol, you adjust the alpha of the symbol, not what is inside it.
