In the past I could use the url to pass a variable using ?pageNum=2 at he end of the url: www.name.com.com/file.swf?pageNum=2

<OBJECT classid="clsid27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0"
WIDTH="790" HEIGHT="190" ALIGN="">
<PARAM NAME=movie VALUE="rsc/flash/float_navigation.swf?pageNum=2">
<PARAM NAME=quality VALUE=high>
<PARAM NAME=bgcolor VALUE=#FFFFFF>
<EMBED src="rsc/flash/float_navigation?pageNum=2" quality=high bgcolor=#FFFFFF WIDTH="790" HEIGHT="190" ALIGN=""
TYPE="application/x-shockwave-flash" PLUGINSPAGE="http://www.macromedia.com/go/getflashplayer"></EMBED>
</OBJECT>

How is it done the new javascript coding below I tried the Flashvars with no success below:

<script language="javascript" type="text/javascript">
if (AC_FL_RunContent == 0) {
alert("This page requires AC_RunActiveContent.js.");
} else {
AC_FL_RunContent(
'codebase', 'http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0',
'width', '900',
'height', '73',
'src', 'rsc/flash/float_navigation',
'quality', 'high',
'pluginspage', 'http://www.macromedia.com/go/getflashplayer',
'align', 'middle',
'play', 'true',
'loop', 'true',
'scale', 'showall',
'wmode', 'window',
'devicefont', 'false',
'id', 'navigation',
'bgcolor', '#fff9f8',
'name', 'rsc/flash/float_navigation.swf',
'menu', 'true',
'allowFullScreen', 'false',
'allowScriptAccess','sameDomain',
'salign', '',
'flashvars', '?pageNum=2'
); //end AC code
}
</script>

Any help would be appreciated.
