X-Cart forums - Dinamic categories menu

I would like to replace the category menu with a DHTML / Javascript menu I have. I edited categories.tpl, inserted there the following code:

Code:

<div id="vqp_comment1" style="position:absolute;visibility:hidden;">

</div>



<div id="vqp_about" style="position:absolute;visibility:hidden;">

****JavaScript based drop down DHTML menu generated by NavStudio. (OpenCube Inc. - http://www.opencube.com)****</div>



<script language="JavaScript1.2" vqptag="datafile" src="new_menu1.js"></script>

<script language="JavaScript1.2" vqptag="doc_level_settings" vqp_datafile0="new_menu1.js" vqp_uid0="311756">



        //Document Level Menu Settings



        cdd__codebase = ""

        cdd__codebase311756 = ""

        cdd__activate_onclick = false

        cdd__showhide_delay = 100

        cdd__url_target = "_self"

        cdd__url_features = "resizable=1, scrollbars=1, titlebar=1, menubar=1, toolbar=1, location=1, status=1, directories=1, channelmode=0, fullscreen=0"

        cdd__display_urls_in_status_bar = true

        cdd__default_cursor = "hand"



</script><script language="JavaScript"  vqptag="loader">



        //NavStudio Code (Warning: Do Not Alter!)



        if (window.showHelp){b_type = "ie"; if (!window.attachEvent) b_type += "mac";}if (document.createElementNS) b_type = "dom";if (navigator.userAgent.indexOf("afari")>-1) b_type = "safari";if (window.opera) b_type = "opera"; qmap1 = "\<\script language=\"JavaScript1.2\" vqptag='loader_sub' src=\""; qmap2 = ".js\">\<\/script\>";;function iesf(){};;function vqp_error(val){alert(val)}

        if (b_type){document.write(qmap1+cdd__codebase+"pbrowser_"+b_type+qmap2);document.close();}



</script><div id="vqp_sfl" style="position:absolute; visibility:hidden;">

</div>



<script vqptag="placement" vqp_menuid="311756" language="javascript1.2">create_menu(311756)</script>

And got this error:

Fatal error: Smarty error: [in customer/categories.tpl line 31]: syntax error: unrecognized tag 'b_type' (Smarty_Compiler.class.php, line 564) in /www/docs/mysite.com/public_html/x-cart/Smarty-2.6.3/Smarty.class.php on line 1082

Any ideas? Is it possible to insert javascript there?
