sharedObject & loadMovie problem

I use “sharedObject “ to load a different “swf” at each page loading. It works properly on my computer but not all on the server. In fact I made three “swf”, the first one imbeds the code and, according to the “Cookie”, loads one of the two other animations. Please take a look at my code and if you have any idea don’t hesitate, let me know. It is quite urgent. Thanks for your help![AS]choix = sharedObject.getLocal(“cookianim”);
index = choix.data.vindex;
trace("Start index= "+index);
if (index == “” || index == “undifined”) {
loadMovie(“banner3.swf”, _root);
choix.data.vindex = “3”;
choix.flush();
index = choix.data.vindex;

} else if (index == "3") {
	choix.data.vindex = "2";
	choix.flush();
	index = choix.data.vindex;
} else {
	choix.data.vindex = "3";
	choix.flush();
	index = choix.data.vindex;
}
anim = "banner"+index+".swf";
index = choix.data.vindex;
getURL("javascript:alert('ok')");
loadMovie(anim, _root);

stop();[/AS]
