Simple Custom Scrollbar (Tutorial error)

Hi. I’ve spent a lot of time through these tutorials the past year. I was working on the Simple Custom Scrollbar tutorial today and noticed an actionscript error. However I don’t know how to fix it. If anyone knows the answer I’m curious.

**The Problem:

**The exmaple on the tutorial page works fine. However when the scrollbar tutorial is completed the up arrow button automatically scrolls the movieclip all the way to the top. This happens even if the button is pressed just for a moment. I’ve checked the code many, many times (that’s where I usually mess up) and the code is the same as the tutorial. So if anyone knows the solution to the code problem I’d be very grateful to know.

Thanks
