So simple in as2, next to impossible in as3....targeting external swf

So I’m trying to do something VERY basic.

I want to load an external swf called ‘signs.swf’ into an empty mc called ‘signholder’.

var loadit2 = new Loader();
loadit2.load(new URLRequest(“signs.swf”));
signholder.addChild(loadit2);

Everything works. Cool. But, I now want to target something within the signs.swf. How do I do it though? What is the path? Do I have to give the child of signholder an instance name? Everything I try fails.

If I wanted the root timeline of the external swf to gotoAndPlay(2) for example,…would i say…

signholder.loadit2.gotoAndPlay(2) ???

var wow:MovieClip = loadit2.content as MovieClip;

wow.gotoAndPlay(2) ???

I am at a loss and this is something that shouldn’t be this hard.
