sharedObject won't work across multiple swf's?

I thought i had sharedObjects figured out… but i want to pull the value from a sharedObject from one swf and change it in another:

i have this for my sharedObject in the main swf…

onClipEvent (load) {
	total = _root.getBytesTotal();
	user = SharedObject.getLocal("sevenBit");
	if (user.data.pIntro == "No") {
		//getURL("http://sevenbit.ws/home.php", "_parent");
		trace("goto site");
	}
	trace(user.data.pIntro);
}

and the button that applies the setting

on(release){
	user = SharedObject.getLocal("sevenBit");
	user.data.pIntro = "No";
	user.flush();
}

thats for the main swf… its an intro… and the setting is to skip the intro completly and remember… but i want to be able to allow the intro to play… if the user wants… so i created a swf to be put in an html page… to activate the intro…

on(release){
	user = SharedObject.getLocal("sevenBit");
	user.data.pIntro = "Yes";
	user.flush();
	trace(user.data.pIntro);
}

i called it right… but it seems like the sharedObject is unique each time… is this true?
