Hi all

In my app I fade a movieclip, and when that movieclip reaches \_alpha=0, I want it to send out a signal to let another movie clip begin to fade in.

How do I do this? Is it something even remotely like:

```auto
firstMC.on(_alpha==0) = secondMC.beginFade;

```

???

EDIT: I don’t want to put any code on movie clips – my code all runs from the root/main timeline.

thanks,

-Nick
