Need Help with loading external swfs

I followed the tutorial for the preloader and transition for dynamic files to a “T”. So I have humbled myself to seek your expert help because I cannot figure it out.
Basically, the initial loaded swf works: _root.section = “blue.swf”;
However when I press any of the buttons on the main swf the transition does not play and the initial swf keeps playing. Its driving me INSANE!!!
This is the first time I am working with externally loaded swfs, and I am sure that its something completely simple. But I have no idea(s) of what it could be. Here’s the code for the buttons:

but1.onRelease = function() {
if (_root.section != “profile.swf”) {
_root.section = “profile.swf”;
_root.transition.gotoAndPlay(“closing”);
}
};
b2.onRelease = function() {
if (_root.section != “resume.swf”) {
_root.section = “resume.swf”;
_root.transition.gotoAndPlay(“closing”);
}
};
b3.onRelease = function() {
if (_root.section != “port2.swf”) {
_root.section = “port2.swf”;
_root.transition.gotoAndPlay(“closing”);
}
};
b4.onRelease = function() {
if (_root.section != “links.swf”) {
_root.section = “links.swf”;
_root.transition.gotoAndPlay(“closing”);
}
};
b5.onRelease = function() {
if (_root.section != “extras.swf”) {
_root.section = “extras.swf”;
_root.transition.gotoAndPlay(“closing”);
}
};

The file that I downloaded from the site works when I test it, and of course, mine doesn’t. I really need everyone’s help, I am completely new to all of this, as if you couldn’t have guessed.
Thanx,
Brian
