Loading random swf file

I totally need help here, I think it is a simple scripting problem that I have.

I have my main movie that loads external swf files into it. Everything works fine unitl i have to make it load random swf files.:frowning:

My loading timeline has a transition with it- so as its loading the swf file it just says loading.

on frame 1 of my transition clip I have this:
_root.section = “intro.swf”;

in the middle of my transition clip I have this:
loadMovie(_root.section, _root.content);
stop();

I want it to be able to randomly load “intro0.swf” , “intro1.swf”, “intro2.swf”

I tried to use the script from this tutorial to load my swf file but it doesn’t seem to work for me
