How to redirect to file picker - onedrive

Question

I am a freshman on skydrive. then I want to use file picker in html, and copy the demo code from Interactive Live SDK. but the running result, the open window is not direct to file picker page, just direct to my setting redirect_uri page. so what's wrong with my demo page? thanks
<script src="http://js.live.net/v5.0/wl.js" type="text/javascript"></script>
<script type="text/JavaScript">

select: "multi",
onselected: onDownloadFileCompleted,

I found the reason. the redirect_uri must same with the filling in the app registeration.
