ActionScript 3.0 :: MovieClip(scrollpane.content).gotoAndStop(2)?

I need to get my main swf A to tell the swf B (swfB is my scrollpane content or source) to gotoAndStop at frame 2 but it doesn't communicate.Here is my code on my main swfA:

Code:
function xbutton (e:MouseEvent):void {gotoAndStop("p1");MovieClip(sp.content).gotoAndStop(2);}
button.addEventListener (MouseEvent.CLICK, xbutton);

Here is my code on frame 2 in swfB:

Code:
stop();
SoundMixer.stopAll();

to better visualise what i am doing; swfA is my website with lots of pages, swfA has one page* that holds my scrollpane, inside my scrollpane is swfB with a flPlayback (*this page is the tv page). when I exit the tv page to another page on my website the tv must stop. swfB has my flPlayBack on frame 1, frame 2 is blank (no tv).

Ps: The code in swfB works fine independently! I know this because tested it by adding a button (when pressed it goes to frame 2 and the code does stop the tv).
