When I use

letter1.setMask(msk1);  
letter2.setMask(msk2);  
letter3.setMask(msk3);

then MC “letter1” is neatly masked by MC “msk1”, “letter2” by “msk2” etc…

but how to do it in an action loop??

for (n=1; n\<=\_parent.parts; n++) {  
letter[n].setMask(msk[n]);  
}

doesn’t work

for (n=1; n\<=\_parent.parts; n++) {  
(“letter”+n).setMask((“msk”+n));  
}

doesn’t work

Can’t seem to find the right syntax, any ideas?
