Answer 1

Thanks for the suggestion, but I already looked before and
after page 6, nothing has changed. I've been trying to create a new
scrollbar with the instructions from the help on the UIScrollBar
component, but the arrows on the scroll bar don't show up.
I have the text in the text box showing up and changing with
each page. But the scroll bars are not working. Here is the AS I
have on frame 1:
NarrativeText_bottom = narrative_text[_root.CurrentPgNumber];
this.createClassObject(mx.controls.UIScrollBar, "my_sb");
my_sb.setScrollTarget(InstanceName_0);
my_sb.setSize(16,InstanceName_0._height);
my_sb.move(NarrativeText_bottom =
narrative_text[_root.CurrentPgNumber];
this.createClassObject(mx.controls.UIScrollBar, "my_sb");
my_sb.setScrollTarget(InstanceName_0);
my_sb.setSize(16,InstanceName_0._height);
my_sb.move(InstanceName_0._x + InstanceName_0._width,
InstanceName_0._y);
// Load text to display and define onData handler.
var my_lv:LoadVars = new LoadVars();
my_lv.onData = function(src:String) {
if (src != undefined) {
InstanceName_0.text = src;
} else {
InstanceName_0.text = "Error loading text.";
._x + InstanceName_0._width, InstanceName_0._y);
// Load text to display and define onData handler.
var my_lv:LoadVars = new LoadVars();
my_lv.onData = function(src:String) {
if (src != undefined) {
InstanceName_0.text = src;
} else {
InstanceName_0.text = "Error loading text.";
When I drag the component to the side of the text box, the
instance name for the text field (InstanceName_0) automatically
populates the _targetInstanceName property of the component, like
it's supposed to. So why are the arrows on the scroll bar not
showing up?? PLEASE HELP! thanks.
