Dynamic unloadMovie

1

Hello, I need some help here to unload some duplicated movieclips.
Sometimes the script is not unload all the movie clips.

And on frame 2, how to say by scripting “not go to next frame if all the movieclips is not unload”?

Well the script is:

frame1

fileToLoad = "flashText1.txt";
if (loadedVar=="yes") {
nextFrame();
} else {
gotoAndPlay(1);
}
mh_entries_X1._visible = false;

frame2

if (entriesCount > 0) {
    for (var i = 0; i < entriesCount; ++i) {
    unloadMovie("mh_entries_" + i);
    }
}

frame3

if (fileToLoad <> ""){
    ran = math.round(math.random()*1000+1);
    this.loadVariables(fileToLoad+"?"+ran,0);
}

frame4

//empty

frame5

if (entriesCount > 0)    {
    myArray1=variable1.split("|");
    myArray2=variable2.split("|");
    myArray3=variable3.split("|");
    var startY = 17;
    if (entriesCount > 0) {
        for (var i = 0; i < entriesCount; ++i) {
            var name = "mh_entries_" + i;
            this.mh_entries_X1.duplicateMovieClip(name, i);
            this[name]._x = -236;
            this[name]._y = startY + ((i-1) * startY) + startY;
            this[name].title = myArray1*;
            this[name].description = myArray2*;
            this[name].urlTXT.text = myArray3*;
        }
    }
    mh_entries_X1._visible = false;
}

frame6

stop();

button 1

on (release) {
    if (_root.pages.scroll.scrolledMC.entriesCount > 0) {
        for (var i = 0; i < _root.pages.scroll.scrolledMC.entriesCount; ++i) {
        unloadMovie("_root.pages.scroll.scrolledMC.mh_entries_" + i);
        }
    }
    _root.pages.scroll.scrolledMC.fileToLoad = "flashText1.txt";
    _root.pages.scroll.scrolledMC.gotoAndPlay(2);
}

button 2

on (release) {
    if (_root.pages.scroll.scrolledMC.entriesCount > 0) {
        for (var i = 0; i < _root.pages.scroll.scrolledMC.entriesCount; ++i) {
        unloadMovie("_root.pages.scroll.scrolledMC.mh_entries_" + i);
        }
    }
    _root.pages.scroll.scrolledMC.fileToLoad = "flashText2.txt";
    _root.pages.scroll.scrolledMC.gotoAndPlay(2);
}

Thanks
