Hi all,  
I’m having problems in setting three variables using a for loop and then passing these variables to my function. I think it’s something to do with the set function I’m using, because my colorFadeTo function claims it’s being passed an undefined variable.  
Can anyone lend a hand?

```auto

for (var i=0; i<circles.length; i++) {
    var current = circles*;
    set (eval("colorVarAsp"+i), new Color(current.background_mc));
    
    current.onRollOver = function():Void {
        eval("colorVarAsp"+i).setRGB(0x003399);
        trace("colorVarAsp"+i)
        colorFadeTo(eval("colorVarAsp"+i));
    };
    current.onRollOut = function():Void {;
        colorFadeAway(eval("colorVarAsp"+i));
    };
    current.onRelease = function():Void {
        trace("circle: "+this);
    };
};

```

Cheers!
