Loading an external SWF and going to specific coordinates

Hi guys

I have menu.swf which loads an external SWF (longmenu.swf)

(I attach an image to explain better)
longmenu.swf has a long background on stage, which scrolls according to what the user clicks. It works fine on it’s own with tweenLite. But what i need to do is to have menu.swf controls to which part of the background it scrolls or appears at once an item on menu.swf is clicked.

Hope that makes sense
