[CS3 AS2] Button Switch IF stament for video player

I am working on a video player that will have different Languages. The problem that i am have is that i can get the video to switch but i cant get the video to switch back. I have uploaded the file and here is the code that i have have a problem with.

lang.onRelease = function() {
if  (play = English)
{
this.gotoAndStop(“spanish”);
ns.play(Spanish);
theVideo.attachVideo(ns);
}
else if (play = Spanish)
{
this.gotoAndStop(“english”);
ns.play(English);
theVideo.attachVideo(ns);

    }
    };

It would be great if someone could help. I need to have this done today.

Thanks
Mike
