[as]passare parametro a funzione.... come?

[tigerjack]

ciao,

ho questo script:

var slideShow:Function = function (target:MovieClip, index:Number, shifting:Number) {
	var other = interceptMovieClip(target);
	var int_index = index;
	var mclo:MovieClipLoader = new MovieClipLoader();
	var mcli:Object = new Object();
	mcli.onLoadError = function(target:MovieClip, errorCode:String) {
		if (errorCode == "URLNotFound") {
			slideShow(target, index, shifting);
		}
	};
	mcli.onLoadInit = function(target:MovieClip):Void  {
		int_index += 2;
		var t:Object = new mx.transitions.Tween(target, "_alpha", mx.transitions.easing.None.easeNone, 0, 100, .5, true);
		t.onMotionFinished = function() {
			var a = setInterval(function () {
				clearInterval(a);
				var t:Object = new mx.transitions.Tween(target, "_alpha", mx.transitions.easing.None.easeNone, 100, 0, .5, true);
				t.onMotionFinished = function() {
					mclo.loadClip("PASSAREVALORE/"+int_index+".jpg", target);
					target.swapDepths(other);
				};
			}, shifting*900);
		};
	};
	mclo.addListener(mcli);
	mclo.loadClip("PASSAREVALORE/"+int_index+".jpg", target);
};

come si può da un pulsante passare un valore a questa funzione?

grazie
