Scrolling JS problem

Well i'm using a scrpit similar to the one pank uses for the news on teamps.

I can get it working fine when there's just one on te page, but when i put to side by side i get my problem

You will see what i mean by looking at it.

try scrolling on both grids and see what happens.

Some help with this would be great!

lol, maybe you need to change the names of the variables for the scroller on the right.

did it work? yes? no? :(

i asked him that already and he said he did that already and that it didn't work. i'm gonna check out the code now, see if i can see anything wrong

[EDIT]
took a look at for about a half an hour or so and messed around with different things and i'm clueless as to what the problem is. this requires paavo's help.
