Hi,  
I need to mask a text or mc by the attached mc from the library.  
I used this code, but it doesn’t work to me:

[COLOR=DarkSlateBlue]  
i = 0;  
function makeMask() {  
\_root.attachMovie(“mc”, “mc”+i, i);  
\_root[“mc”+i].i = i;  
\_root[“mc”+i].num = i+1;  
\_root[“mc”+i].\_x = 60;  
\_root[“mc”+i].\_y = 50+16\*i;  
\_root[“mc”+i].asBut();  
i++;  
if (i\>6) {  
clearInterval(id);  
}  
}  
id = setInterval(makeMask, 200);  
Text.setMask(mc);[/COLOR]

Could someone please help me?  
Thank you.
