How to make Sliding Menu not reset?

Hi, Kirupa forum (I love this site!!).

I’m using a pretty basic scroll similar to:
http://www.kirupa.com/developer/flash5/slidingmenu.htm

However, my content exceeds the size of the flash doc, so I’m using left and right buttons to move left and right. My question is, how can I have each unique URL open with the scroll area set with the selected image centered (rather than resetting)?

Here’s my (not yet live) site: http://xlties.com/shop/product_info.php?products_id=31 Notice that selecting another images resets with each click. . .Anyway to handle this dynamically? The only way my non-programmer brain thought to fix this was to make unique scroll areas for each product, but there MUST be a better way!

Help!

Thanks in advance.
