No joke, this is what my PC tells me for an \_alpha value. It starts with 0 and is increased by 10 10 times (10x10=100), but the \_alpha is not 100% after that, that’s for sure. So can somebody tell me why a calculator ist calculating wrong? Would really interest me! 😏

“alf” just gives me the \_alpha value in a dynamic textfield.  
“att” ist for control if the step var causes the problem =\> it does not.

```auto

// customize
fps = 20;
fadeLength = 0.5; // seconds

// init
i = 0;
length = fps * fadeLength;
step = 100 / length;
att = 0;
_root.pic1.loadMovie("pic1.jpg", "pic0", 1);

// load
function loadPic(newPic) {
	_root.pic2._alpha = 0;
	_root.pic2.loadMovie("pic"+newPic+".jpg", "pic2", 2);
	_root.onEnterFrame = function() {
		_root.pic2._alpha += step;
		alf = _root.pic2._alpha;
		att += step;
		i++;
		if(i >= length) {
			_root.onEnterFrame = function() {
				oldPic = newPic;
				_root.pic1.loadMovie("pic"+oldPic+".jpg", "pic1", 1);
				_root.onEnterFrame = function() {};
				i = 0;
			}
		}
	}
}
_root.nav.btn1.onPress = function() {
	loadPic(1);
}
_root.nav.btn2.onPress = function() {
	loadPic(2);
}
_root.nav.btn3.onPress = function() {
	loadPic(3);
}

```
