I wanna make a rollover Banner

[Venian]

Hi.
I want to make a rollover banner which when i move to cursor over it will expand over the website and will contract if i move the mouse off of it.
I wonder how can i do that? Because if i have a motion tween which expands the movie clip on the stage lets say from 200 height to 400 height the exported swf has 400 height anyway and i will not be able to use a part of the site because of the flash.

So i want to make it resize the stage when i start the motion tween. And back to 200 when i roll out.
How can i resive the whole document from within flash using AS 2?

Thanks.

you can't resize the document from within flash. you'll need to use something like javascript with your flash.
