ASP Variable Help

Hi i got a mini player im building, one track just a single mp3 to be played. this is brought in via asp from a database.

On My First Frame i have…

mySound1 = new Sound();
    strMP3 = MP3;
    loadVariables("getdetailstrack.asp", "0");
    trace(MP3);


theres a little preloader code on a blank MC as well but that shouldnt be a problem as works fine already…

and my play button code is…

// Play
on (release) {
    _root.nextSound = 1;
    _root.playMe = 1;
    _root.mySound1.loadSound("mp3/"+ strMP3 +".mp3", false);
    
}

but for some reason its not picking up the mp3 name - the getdetails page is fine also and returns mp3=thedaveyb.mp3

any ideas?
