Referring to movieclip in button

Uncategorized

hi,

i was using this function

this.onEnterFrame = function() { 
 if (picture._alpha>50) {
  picture._alpha -= 10; 
 }
};

for a movieclip on the parent level, and it was working fine.

However i need this movieclip to be in a button.

What do i have to change in the coding for that to work?

thanks!
