HELP! - Transition Between Exteral SWF

programming flash
1

I am using the Transitions Between External SWF Tutorial, I am having some troubles and would greatly appreciate any and all help.

I have a base layer where all the nav loaded externally. I applied the script to the buttons on the nav and works flawless.

In the SWF that it loaded by the nav I use the script again and is as follows:

on (release) {
    if (this.currMovie == undefined) {
        this.currMovie = "Content/Artist/Shantelle/bio";
        this.artistcontent.loadMovie("Content/Artist/Shantelle/bio.swf");
    } else if (this.currMovie != "Content/Artist/Shantelle/bio") {
        if (this.artistcontent._currentframe >= artistcontent.midframe) {
            this.currMovie = "Content/Artist/Shantelle/bio";
            this.artistcontent.play();
        }
    }
}

and the script on the final frame of the loaded SWF is:

this.artistcontent.loadMovie(this.artiscontent.currMovie+".swf")

This works, but when you click another button the SWF unloads and plays again.

ANY IDEAS WOULD BE GREATLY APPRECIATED, please ask if you need any clarification.

Thanks in advance for your help
