i got one problem here…  
i got a array which stores some elements, in string form, and these elements actually represent the name of the instances on the stage. now i want to trigger the instance to reset it’s alpha value…  
how i dont know how it works.

eg:  
i got an array[“A”.“B”.“C”];  
Instances name available: A,B,C,D…Z  
now how i should do to make the instance A to got triggered?? i call them by using on button.

i try some like \_root.name.array[0]=\_alpha=0;  
but not success.
