Problem with external quiz navigation

Hello All,
I am designing an online course and I am using the FLMX2004 quiz template.
I have divided the course into 10 swf files, 5 for each section’s content, and 5 for each quiz.

The problem is, I am loading the external swf files into a main swf using an empty movieclip. When I load the quizzes externally the navigation arrows dont work.
here is the code to load the quiz (external swf):
on(release){
unloadMovie("_root.content");
loadMovie(“Section1Quiz.swf”,_root.content);
}
here is the code on the nav button within the quiz:
on (release) {
_parent._parent.QuizTrack.setNewPage();
_parent.updateFrame();
gotoAndStop(2);
}
I can send links of the work, if needed.

Also, how do I expose the total score, so that I am able to use it in conditional statement. If the user scores less than 70%, they are asked to try again? If more than 70%, they go to the next section.

This is my first project, I have been working on it for days, and I seem to be stuck. Please help! :hurt:
