Using elements not defined in first frame of a movieclip

Hi all :slight_smile:

I’ve finally made the leap in to AS3 - it seems much nicer and easier than any of its predecessors but I’m still getting stuck on the odd thing.

This is something I haven’t been able to resolve with Google:

I have a movieclip with an instance name “myMC”. On the first frame inside myMC I have another movieclip called “point”. On the second frame inside myMC I have a movieclip with instance name “smallBox”.

This works:
myMC.point.transform.colorTransform = c;

This does not:
myMC.smallBox.transform.colorTransform = c;

Do I need to do something to indicate I’m working on frame 2?

Ta,
lenny
