Hello everyone!  
I am using this code, but for some reason it doesnt work…  
I have all the movie clips (mc\_effect\_1 to mc\_effect\_750) on my stage.  
Why it doesnt work?  
Any clues?  
Thanks.  
Cheres.  
Leo.

```auto

var i =0;
while (i < 751)
{
    _root.mc_list_streets["mc_effect_"+i].onRollOver = function ()
	     {
  		_root.mc_list_streets["mc_effect_"+i]._alpha = 30;
     };
	i++;
}

```
