What’s good, Kville? I’ve searched the forums, the tutorials and a book or two and still can’t figure out why this doesn’t work right. So, this is a last resort. Feel free to flame me for asking a nøºß question, but here goes.

I have a button! I want this button to change the .\_alpha value of a movie clip. When you click it the first time, I want the .\_alpha of the MC in question to go from 0 to 50, on the next click 50 to 100 and on a third click 100 back to 0. I don’t know why this doesn’t work, it should (at least that’s what my current understanding tells me, but since it dosn’t work, I’m clearly wrong).

Here’s the .FLA. Thanks in advance!
