New to As3,…noticed that the usual logic of just saying ‘parent.do\_something’ doesn’t work, cause it’s saying that I am trying to access an undefined thing.

So, I want to have my externally loaded swf tell it’s parent mc to gotoAndPlay a certain frame.

I have tried to understand Static vars, but I do not know how to implement this, and it’s sort of essential.

Not sure if I need to create a separate .as file that states some variables that I can access in sub swfs later…or what.

Help?

Thanks
