Once again, As3 makes something simple, totally incomprehensible

all i want to do is something very basic.

Load in a swf into an mc.

My website has five buttons, I have five external swfs that need to be loaded into the same mc.

In AS2, it’s just loadMovie(“whatever.swf”, this.myMC)

And if I repeat the command, the new swf will just replace the old one.

As3 seems to be a complete cluster f#$% when it comes to doing much of anything. Cryptic error messages that don’t help…etc.

I’ve been trying addChild, and loader class, and all this, but I can’t removeChild before I add a new one.

How can I do what I want in AS3?
