telltarget/control movie in another html document

I have a framset: an upper frame and main frame. Both contain htm pages with flash files in them.

There are buttons in the Main frame that load different htm files into the same frame (_self). When one of these buttons is clicked, I want the flash file in the upper frame to be effected (move to a frame, play a mc etc.) Is this possible?

Yes, it's possible, but the only way to do it is to use javascript. Have a look at: http://www.moock.org/webdesign/flash...d/#2directions
