If I have movieclip named box01\_mc inside movieclip btn01\_mc and I wanted to change box01\_mc’s alpha to 0 on the rollover of btn01\_mc how would I write this? I tried writing the following code on btn01\_mc but it didn’t work:
on (rollOver) {
box01\_mc.\_alpha = 0
}
Thanks!

That code is correct, are you sure you’ve given your instance an instance name ? Not a symbol name in the library, an instance name.

Skribble - in static event handlers such as on(rollOver), this isn’t necessary.
