How does Captivate 4 function once imported into and now within Flash 4 (AS3 environment)?

Question

I have a specific need to try to get a handle on a certain section of the timeline to add a textbox with certain text in it.  if (label.name == "Slide_3") {then... display the textbox and the text } does not work.  I am trying to use the addChild method to display the textbox and its text in the displayList during the Slide_3 section of the timeline.  This may not be the way to go as I can't seem to get it to work...
My Goal: 
Using AS3, working from within Frame1 coding area (Timeline scripting area), have some text appear in a textbox but only while Slide_3 is playing.
I already have written the code that pulls text in from an XML document, stuffs it into a dynamically created textboxand, and  am trying to take some of the text and have that text only appear during a certain part of the timeline. 
Assumptions:
The standard/native way that a Captivate.cp file is imported into Flash CS4 results in a timeline that has labels (Slide_1, Slide_2, Slide_3, etc.)
I don't want to manually create a textbox and manually put the text into it on the Actions frame of the Slide_3 label, but instead would like to put the text into the text property of the textField programatically from Frame1 (Action frame in Frame1 + F9)
I have tried using the addChild method but that adds the textbox to the WHOLE timeline. (Creating a textbox is not a problem, but instead getting some text into the textbox only during Slide_3 is the issue)
The Problem:
How can I get the text to only appear during the playing of the Slide_3 label frames? (But NOT display during the rest of the timeline)
When I run code on the Action frame of Slide_3 that outputs the displayList, I get the following:
root1 [object MainTimeline]
     info_txt [object TextField]
// this is a textfield that i created
      instance3 [object TextField]
      Slide_3 [object Slide_3_7]
           instance15 [object Shape]
           instance16 [object MovieClip]
                instance17 [object Shape]
           instance18 [object clickbox4_9]
                click_zone [object SimpleButton]
                instance19 [object Shape]
           instance20 [object Shape]
           instance21 [object Shape]
           instance22 [object Shape]
      SlideClip3 [object MovieClip]
Yet, when I trace the keyword *this* (from within the Action frame in Slide_3) Flash outputs [Global Object].
I am wondering how I can display the specific text for Slide_3 only during the playback of Slide_3. I'm guessing that, if I could only find what the Global Object is, I could addChild to its display list property.
I also tried using some of the Static variables to no avail (that were automatically created when the import occurred) such as:
var ref=this;
var nCurSlideIndex:Number;
var currentSlide_mc:MovieClip;
var quizPlaybackController;
var scrubberChanged:Boolean;
var slideNewFrame:Number;
var mcLoader:Loader = new Loader();
var loading_sub_mc:MovieClip;
var m_preloaderLoaded:Boolean = false;
Any guidance, suggestions, ideas, that you have would be very welcomed! 
Some Things that I've Tried:
Incidentally, when I write code in the main timeline (Frame1 and press F9) I get some of the following behavior:
//this.Slide_1.addChild(info_txt); //displays the textbox with text but only during "slide 1"
//this.addChild(info_txt); //displays textbox and text during the whole timeline
//SlideClip1.addChild(info_txt); //displays textbox and text only during "slide 1"
//SlideClip3.addChild(info_txt); //nothing displays --TypeError: Error #1009: Cannot access a property or method of a null object reference.
//ref.addChild(info_txt); //displays textbox and text all the time
//addChild(info_txt); //displays textbox and text all the time
//ref["Slide_3"].addChild //no luck here either

I don't have any insights into this particular problem. But we are having strange things happen with Captivate and imported AS3 animations. never had problems witht he AS2 animations. so, we are having to recreate and everything and republish as as2.
