Excel Web app embed codes

With Excel Web app we can embed spreadsheets. This gives huge possibilities to creat i.e web based calculators. Excel offers HTML embed code (works) and an Java Script code (doesn’t work). Can anyone tell me why this JS won’t work:
I´ll pay for solutions…

Iframe embed
<iframe width="211" height="252" frameborder="0" scrolling="no" src="https://skydrive.live.com/embed?cid=DC6847B853F9E695&resid=DC6847B853F9E695%21119&authkey=&em=2&AllowTyping=True&Item='Ark1'!Utskriftsomr%C3%A5de"></iframe>

JS embed

<div id="myExcelDiv" style="width: 211px; height: 252px"></div>
<script type="text/javascript" src="http://r.office.microsoft.com/r/rlidExcelWLJS?v=1&kip=1"></script>
<script type="text/javascript">
	/*
