There is a good chance I just totally fail at the internet, but I can’t seem to find any posting about how to make a super simple alpha tween on rollover.

I want a box to go from 0 - 100 alpha when the mouse rolls over, and then back to 0 when it rolls out. Of course, if the mouse rolls out before the alpha hits 100, it should still fade back to 0.

I am really new to flash, but I learned how to get the box to fade from 0 - 100 on its own… I just don’t know how to tie it to a mouse event.
