UIScroll Bar, Remove when not needed

Question

Hello,
I just finished the 3D carousel tutorial on gotoandlearn. My
questions is, I added a scroll bar to the rigt of the text field
because on some of the content for the icons there is too much
information to show up on one page. Problem is, the scroll bar
shows up while the Carousel is spinning around as well as in pages
(movies) that only have a couple lines of text. I'd like to know
how to get rid if this.
I looked up this issue on the web but most "finds" I found
were only about removing the toolbar when there is not enough text
to warrant a scroll bar. Keep in mind that I m less than a novice
when it comes to script.
Thanks all.

Thanks again for looking at this....

// bottomScrollV checks how many lines of text there are
// So,...if you have a textfield with 10 lines of visible
text and to show more, you need a scrollbar:
if(sb.bottomScrollV>5){
sb.visible = true; // show scrollbar
}else{
sb.visible = false; // hide scrollbar
down_btn.onPress = function() {
theText.scroll += 1;
up_btn.onPress = function() {
theText.scroll -= 1;
