AS2- Array for naming buttons and loading movies

I’ve got about 50 buttons onstage with names like btn1a_mc, btn2B_mc, etc. Each one loads an external swf (called “Monosem1Aslideshow.swf”, where the “1A” corresponds to the button name.) into a movieclip holder called slideHolder_mc. I’m trying to use an array instead of writing code for each button. I’m using the following:

buttonNumber = ["1A", "2B", "3C", "4D", "1E", "2F", "3G"];

for(i=0; i<buttonNumber.length; i++){
    var btnName:String = "btn"+*+"_mc";
    MonosemBtns_mc.btnName.onRelease = function(){
        loadMovie("002Assets/Monosem"+*+"slideshow.swf", slideHolder_mc);
        };
    };

But I can’t seem to get it to work. I’m a little shaky on array syntax and can’t find a tutorial that addresses my particular problem.

Any help would be appreciated!
