Scroll problem!AAGGHHHH

I posted up a question a couple of days ago and received some feedback but not the amswer to my problems. After going to other forums I still didn’t get the problem solved so here we go again…final attempt.

download the file at www.buildrebuild.com

It is a scrolling movie clip with xml file. The thing I want to get working is if the number of xml nodes or buttons added to the movieClip is less than 10 the scroller won’t need to scroll.
You’ll see the problem if you delete a few of the lines in the xml file to leave, say 5…the movieClip scrolls the items down to the bottom. I want the scroll to be disabled if there are less than 10.

Any help much appreciated.

Thx
