Preloader help

Hey all,
This has probably been covered before, but how do you get a preloader to load only the first scene? I’m making a flash website, and I would like it to just load the first scene, and then load the others as i go to them, or as the user sits at the first page. I’m currently using the

if (this._framesloaded>=_totalframes) {

script. Can I use:

if (this._framesloaded>=60) {

Where 60 is the number of frames in the first scene.
I want to make this site easy to use, and not too annoying when it comes to loading. Thanks in advance.

Link to the site in question: (Warning long load! approx. 2MB)
