Loading issues

This is my first brave attempt at tweening using all actionscript, so bare with me! :stuck_out_tongue:

Here is my issue:
I click on the booking link and everyhing loads just fine, however, if I click on it again it only loads partially. Can anyone tell me why this is and how to resolve?

Here is the link:
http://laughwithlarry.com/index.swf

Here is the AS for the booking button:

on(release){
    unloadMovieNum(2);
    loadMovieNum("booking.swf",2);
}

The AS for the booking page:

stop();


setInterval(fadeInFunction, 800);
counter = 0;
function fadeInFunction() {
    counter++;
    _root.Increment(counter, 100, 2);
}
function Increment(count, maxAlpha, speed) {
    _root.onEnterFrame = function() {
        _root["MovieClip"+count]._alpha += speed;
        if (_root["MovieClip"+count]._alpha>=maxAlpha) {
            _root["MovieClip"+count]._alpha = maxAlpha;
            delete _root.onEnterFrame;
        }
    };
}

**Also, here is the code for the index page where the links fade in:
**

loadMovieNum("home.swf",2);


setInterval(fadeInFunction, 800);
counter = 0;
function fadeInFunction() {
    counter++;
    _root.Increment(counter, 100, 2);
}
function Increment(count, maxAlpha, speed) {
    _root.onEnterFrame = function() {
        _root["MovieClip_mc"+count]._alpha += speed;
        if (_root["MovieClip_mc"+count]._alpha>=maxAlpha) {
            _root["MovieClip_mc"+count]._alpha = maxAlpha;
            delete _root.onEnterFrame;
        }
    };
}
