Actionscript not working

I am trying to get a header to play only once...so, have it play fully on the home page but when we go to other pages, not play the whole thing.  I found the following code online and it works to the extend that if always goes to frame 100 but regardless of whether I clear the cache or cookies.  The first part never executes (gotoAndPlay(3).  Please help.Start Free Trial

replay = SharedObject.getLocal("save");
 
if (replay.data.name == undefined){
gotoAndPlay(3);
replay.data.name = "played";
} else {
gotoAndStop(100);
}
