I need a hand with buttons

i have made a few buttons, made a scrollpane,put a swf file 2 the scroll pane but when i click on the button i want it 2 change the swf file in the scroll pane to display my content. i was using the add new scene thing but when i make a new scene it gives me a blank page and i have to copy my webpage to that scen as well so is there a way to just change the swf file displayed in the scroll pane?
