Need help with Kirupa custom scroller-please

Hi.

I integrated the Kirupa custom scrollbar.

It’s this one.

It’s working great but it has one little glitch that I haven’t been able to fix.
When you press on the “up” arrow, it lowers the content the height distance of the “scrollface”.

I figured out it has something to do with the initial position, but haven’t had any success fixing it.

Here’s where I’m using it so you can see what it’s doing.
