I have the following code  
[AS]si = setInterval(function () {  
ind++;  
ind\>7 ? clearInterval(si) : null;  
var tw = new Tween(\_root.\_mc[“a”+ind], “\_xscale”, Regular.easeOut, 0, 200, 60);  
new Tween(\_root.\_mc[“a”+ind], “\_yscale”, Regular.easeOut, 0, 200, 60);  
tw.onMotionFinished = function() {  
new Tween(\_root.\_mc[“a”+ind], “\_xscale”, Regular.easeIn, 0, 100, 40);  
new Tween(\_root.\_mc[“a”+ind], “\_yscale”, Regular.easeIn, 0, 100, 40);  
};  
}, 50);  
[/AS]Basically, it goes through 7 loops and animates each object. My problem is that the onMotionFinished function isnt being triggered because it gets overwritten each time before it can. is there a way to dynamically create a variable name to keep track of each Tween? Something like [AS]var eval(“tw” + ind) = new Tween(\_root.\_mc[“a”+ind], “\_xscale”, Regular.easeOut, 0, 200, 60);  
eval(“tw” + ind).onMotionFinished = function() {[/AS]except eval appears to only work for objects. Any ideas? 🙂
