Hello, I'm wondering if anyone can help me out there. I'm creating a rollover button that has an alpha effect of 70% laid over a bitmap image to give the effect; which when rolled over will fade to an alpha of zero in turn revealing the bitmap below. My problem is that I can't get the rollover right. I have tried creating a movie clip of the fade and drop it into the over state of the button but it doesn't work. I have also tried to create a basic script action to do this but that has also failed.....can anybody help me??????

Thanks
