External SWF's 'Only load once, and does not reload second time'

Hey.

Alright i have done this tutorial ([COLOR=MediumTurquoise]http://www.kirupa.com/developer/mx2004/transitions2.htm[/COLOR])… And it works but i can only get the swf’s to load one time, and if i load another swf via a button i can not load the previous swf again…now i do no it is because i am using MC buttons cause i have try’d both methods and the other way works…
Here is my AS on my buttons, any help would me alot…

[COLOR=SeaGreen]this.onRelease=function(){
if (_root.currMovie == undefined) {

_root.currMovie = “resume”;
_root.container.loadMovie(“resume.swf”);
} else if (_root.currMovie != “resume”) {
if (_root.container._currentframe >= _root.container.midframe) {

_root.currMovie = “resume”;
_root.container.play();
}
}
