How do I make buttons load new SWFs?

Hi hope someone can help,
I currently have this site up
As you can see there is a problem when pressing buttons from page to page the scroll bar stays at the same position- I would like to put these buttons at the bottom of the page but with this problem its not practical.
Do I Action script the buttons so that they load new SWF files?(If so what is this code?)Therefore making each individual page a new SWF, instead of all being in one main stage like they are now. Will this solve my problem by resetting the scrollbar to the top when it loads a new file?
Please help as this problem has been buggin me for a while eventhough its probably really simple!
