Load internal SWF and control other SWF

Question

I have 96 questions with radio button responses that control
movie clips. They are all in the same swf but I want to separate
the questions and put them in a draggable, scalable movie clip so
that the user could move the question box as convenient. Most of
the ActionScript is associated with the MCs, responding to a radio
button listener object. The two SWFs must advance from frame to
frame synchronously.
Here is what I did:
1. Split the original FLA into 2 pieces, a MC FLA and a
Question FLA
2. Renamed rbListener as _global variable in MC FLA
3. Used this code in the MC FLA:
this.createEmptyMovieClip("loadQuestions_mc",
this.getNextHighestDepth());
loadQuestions_mc._height = 400;
loadQuestions_mc._width = 600;
loadQuestions_mc.onPress = function():Void {
this.startDrag();
loadQuestions_mc.onRelease = function():Void {
this.stopDrag();
loadQuestions_mc.createEmptyMovieClip("containQuestions_mc",
this.getNextHighestDepth());
loadMovie("mccolor4_SplitBottom.swf", containQuestions_mc);
4. Used this code in the first frame of Questions FLA:
function specifyListeningTargets () {
i = cellNumber;
eval("QA" + i).addEventListener("click", rbListener);
eval("QB" + i).addEventListener("click", rbListener);
eval("QC" + i).addEventListener("click", rbListener);
// Button pops up at x:400, y:600, What is 10? Depth?;
clicking button advances to next frame.
function popupNav () {
i = cellNumber
if (((eval("QA" + i).selection.data) > 0),
((eval("QB" + i).selection.data) > 0),
((eval("QC" + i).selection.data) > 0)) {
this.createClassObject(mx.controls.Button, "popupNext_btn",
10, {label:"Go To Next Questions"});
popupNext_btn._width = 20;
popupNext_btn.move(250, 375);
function popupClicked() {
this.nextFrame();
_parent.nextFrame();
popupNext_btn.addEventListener("click", popupClicked);
5. Used this code in each frame of the Questions Fla:
stop();
cellNumber = 1;
popupNext_btn._visible = false;
popupNav ();
specifyListeningTargets();

Answer 1

yes and yes: wait until loading is complete and then
reference the target movieclip or _level of your loadMovie(),
loadMovieNum() or loadClip() method.
