hey I have a couple buttons within a movie clip of a ScrollPane that are not working. This is my exact code, how do i get them to work?

scrollPane.source = myContent;
scrollPane.setSize(173,500);

K1Button.addEventListener(MouseEvent.CLICK, playVid);

function playVid(e:MouseEvent):void{
myVideoPlayer2.myFLV2.source = “video/K.mp4”;
myVideoPlayer2.myFLV2.play();
}

T1Button.addEventListener(MouseEvent.CLICK, playVid2);

function playVid2(e:MouseEvent):void{
myVideoPlayer2.myFLV2.source = “video/T.flv”;
myVideoPlayer2.myFLV2.play();
}
