Help: Smooth scroll to fixed positions (horizontal in div)

[Jeroen]

Dear all

I've been trying and trying, but i'm not a programmer, and i can't get this
to work or find a solution out there on the net... so.. let's try in here

I'm close to something, but just lack that elegant touch... a smooth scroll
or "ease in/ease out" to fixed positions, ie steps of each 450 pixels.

What I have now works, apart from the obvious fact that the scroll happens
instantanious.

Please have a look: www.jeroen.dk/scroll_divs2.html

What I would like is that when the next and previous links are pressed, the
scroll to the next or previous position happens with an ease-in effect.

Hope this is understandable and that someone can help me find a solsution or
provide one.

Thanks
Jeroen
