Trouble getting html to center flash site

What do I need to change in this html
… to get my webpage to be centered. Currently it’s line up to the left. I have done some searches, and tried to change different things, but my lack of any html knowledge hinders me. below is the portion of my html script that I think is the culprit.please help

</script>
<noscript>
<object classid=“clsid:d27cdb6e-ae6d-11cf-96b8-444553540000” codebase=“http://download.macromedia.com/pub/s…ersion=9,0,0,0” width=“900” height=“850” id=“wire1” align=“top”>
<param name=“allowScriptAccess” value=“sameDomain” />
<param name=“allowFullScreen” value=“false” />
<param name=“movie” value=“wire1.swf” /><param name=“quality” value=“high” /><param name=“scale” value=“noscale” /><param name=“bgcolor” value="#ffffff" /> <embed src=“wire1.swf” quality=“high” scale=“noscale” bgcolor="#ffffff" width=“900” height=“850” name=“wire1” align=“top” allowScriptAccess=“sameDomain” allowFullScreen=“false” type=“application/x-shockwave-flash” pluginspage=“http://www.macromedia.com/go/getflashplayer” />
</object>
</noscript>
</body>
</html>

Please be specific is your could since I know absolutedly nothing about html syntax or coding.
