[RazorWriter]

I get Smarty errors whether I put a javascript in home.tpl, or the actual body of the page I'm working on.
the script is:

<script language="JavaScript">
<!--
function MM_openBrWindow(theURL,winName,features) { //v2.0
  window.open(theURL,winName,features);
}
//-->
</script>

and the error:

Fatal error: Smarty: [in help/customer_service.tpl line 6]: syntax error: invalid attribute name - 'window.open(theURL,winName,features);' in /home/www/urbanhomemaker/store/Smarty-2.3.0/Smarty_Compiler.class.php on line 1398
