Custom Scrollbar Options

[sikdragon]

I seem to have stumped all the xanga help people that are on at 5:30 once again in my 3 days.

Ok i tried to put a custom scroll on my boxed xanga which is a div and lets say the div's id is xanga226892, what the hell did i do wrong? this thing took me forever. this code was all in the custom header. the pic links are bad i know but it shouldnt effect the whole thing. when i hover over the buttons it says "object expected". As far as i can tell all the objects are in place.

CODE
