Fscommand and javascript

On my page there is a code like this

<script type="text/javascript">
   var pageViewerID = 11196489;
   var pageOwnerID = 10000000;
   var pageViewerFName = "Vkey";
   var pageOwnerFName = "WHATEVER";
   var pandoraRegFlag = '-1';
</script>

If i type this script to the Address bar


javascript:alert (pageViewerID)

A message alert will appear saying the pageViewerID wich is “11196489” right?

How should i put this on flash fscommand? is it like this

fscommand("alert", "Hello, "+pageViewerID+", welcome to our website!");

And is it possible that the pageViewerID will save to an text file on my ftp?
