Simple preloader assistance needed

Tnx for your time. Here’s the deal.

I’d like to create a very simple preloader, but I couldn’t find anything on the net about it. Because it’s a shape tween, I guess.

The preloader itself is supposed to be a line that shape tweens from a dot, centered in the middle of the screen (a flash movie) to a 900px line also centered in the middle of the screen. So the line stretches to the left and the right. And i need a percent loaded text that just sits below that line, centered.

Hope you can help!
