guys any of you have any idea how to achieve this?  
I have 16 movie clips on stage and i want all of them to be masked with another movieclip from the library.

here’s the script i use, but it’s all just rough guess, it needs major modification:

[AS]  
import flash.filters.DropShadowFilter;  
var drop:DropShadowFilter = new DropShadowFilter(0, 45, 0x000000, .6, 5, 5, 1, 1, false, false, false);  
for (var i = 1; i\<17; i++) {  
this[“mc”+i].onEnterFrame = function() {  
this.filters = [drop];  
this.attachMovie(“maskIN”, “mask”, 0, {\_x:this, \_y:this});  
this[“mc”+i].setMask(mask);  
};  
this[“mc”+i].onRollOver = function() {  
mask.gotoAndPlay(2);  
};  
this[“mc”+i].onRollOut = function() {  
mask.gotoAndStop(1);  
};  
}  
[/AS]

anyways here’s an attachment, please help!
