Again we're seeing the conflict between serverside and clientside 
languages, but this time a solution is easy to find.
Here's an example of how to do it, I'm sure this won't need any 
further 
explanation *g*:
<script language="JavaScript">
<?
  $phpVar = 25;
  echo("var myVar = ".$phpVar.";");
?>
</script>

     ...and, just for complete information, it can also be done this 
way:
<?
  $phpVar = 25;
?>
<script type="text/javascript">
<!--//
var myVar = <%=$phpVar%>;   // for numeric values
var myVar = "<%=$phpVar%>"; // for string values
//-->
</script>
