Playing multiple copies of the same swf at the same time

I have a problem with Playing multiple copies of the same swf at the same time.

The thing is that I want to have a button and when pressing the button I want to load a swf file. I want the file to load at diffrent position everytime and I also want it to remain visible when Im pushing the button another time for another copy.

I got this code so far but it only plays one copy of the swf at the time.

but.onPress = function () {

_root.createEmptyMovieClip(“samlat”,1);

    samlat.loadMovie("kanin.swf");

    
         var xrandom = Math.round(Math.random()*300);
         var yrandom = Math.round(Math.random()*300);
     
            samlat._x =  xrandom ;
            samlat._y = yrandom ;

}

how should the code look like? I have tried with loadMovieNum but then I cant position the swf.

I also tried this

but.onPress = function () {
var nr = Math.round(Math.random()*300);

    trace(nr.toString());
    namn="samlat";
    nummer=nr.toString();

_root.createEmptyMovieClip(namn+nummer,1);

    namn+nummer.loadMovie("kanin.swf");

    
         var xrandom = Math.round(Math.random()*300);
         var yrandom = Math.round(Math.random()*300);
     
            namn+nummer._x =  xrandom ;
            namn+nummer._y = yrandom ;

but then no swf at all shows up.

any idea what to do??
