So, for this button I want it to make a flashing animation from grey to red. It is supposed to play the animation in a loop, although, when I rollout with my cursor it should finish the current fading animation. Anyone who could offer some help?

And also, but I couldn't get it into the title. I want the background to be transparent. What am I overlooking?

I upped the swish file: http://home.orange.nl/mfranssen/button.swi

So if anyone could tell me what I'm overlooking or forgetting, I'd really appreciate it
