Menu Dropdown pára de funcionar com botão de "Subir ao Topo"

No meu blog tem um menu dropdown instalado,

mas toda vez que eu tento instalar o código de "subir ao topo"

ele pára de funcionar.

Eis o código do botão:

<script type="text/javascript" src="[http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js">](http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js)

<script type='text/javascript' language='Javascript'>
var scrolltotop={

//startline: Integer. Number of pixels from top of doc scrollbar is scrolled before showing control //scrollto: Keyword (Integer, or "Scroll_to_Element_ID"). How far to scroll document up when control is clicked on (1=top). setting: {startline:100, scrollto: 0, scrollduration:1000, fadeduration:[500, 100]}, controlHTML: '<img src="http://1.bp.blogspot.com/-_D_P2qDHH1M/UlHKu14vvoI/AAAAAAAAKgk/IZ5Hlb4uCPE/s1600/topo8.png"/>' //HTML for control, which is auto wrapped in DIV w/ ID="topcontrol" controlattrs: {offsetx:5, offsety:5}, //offset of control relative to right/ center of window corner anchorkeyword: '#top', //Enter href value of HTML anchors on the page that should also act as "Scroll Up" links state: {isvisible:false, shouldvisible:false}, scrollup:function(){ if (!this.cssfixedsupport) //if control is positioned using JavaScript this.$control.css({opacity:0}) //hide control immediately after clicking it var dest=isNaN(this.setting.scrollto)? this.setting.scrollto : parseInt(this.setting.scrollto) if (typeof dest=="string" && jQuery('#'+dest).length==1) //check element set by string exists dest=jQuery('#'+dest).offset().top else dest=0

this.$body.animate({scrollTop: dest}, this.setting.scrollduration);
},
keepfixed:function(){
var $window=jQuery(window)
var controlx=$window.scrollLeft() + $window.width() - this.$control.width() - this.controlattrs.offsetx
var controly=$window.scrollTop() + $window.height() - this.$control.height() - this.controlattrs.offsety

this.$control.css({left:controlx+'px', top:controly+'px'}) },

togglecontrol:function(){
var scrolltop=jQuery(window).scrollTop()
if (!this.cssfixedsupport)

this.keepfixed() this.state.shouldvisible=(scrolltop>=this.setting.startline)? true : false if (this.state.shouldvisible && !this.state.isvisible){ this.$control.stop().animate({opacity:1}, this.setting.fadeduration[0]) this.state.isvisible=true } else if (this.state.shouldvisible==false && this.state.isvisible){ this.$control.stop().animate({opacity:0}, this.setting.fadeduration[1]) this.state.isvisible=false } },

init:function(){
jQuery(document).ready(function($){
var mainobj=scrolltotop
var iebrws=document.all

'fixed' : 'absolute', bottom:mainobj.controlattrs.offsety, right:mainobj.controlattrs.offsetx, opacity:0, cursor:'pointer'}) .attr({title:'Subir ao Topo!'}) .click(function(){mainobj.scrollup(); return false}) .appendTo('body') if (document.all && !window.XMLHttpRequest && mainobj.$control.text()!='') //loose check for IE6 and below, plus whether control contains any text mainobj.$control.css({width:mainobj.$control.width()}) //IE6- seems to require an explicit width on a DIV containing text mainobj.togglecontrol() $('a[href=' + mainobj.anchorkeyword +']').click(function(){ mainobj.scrollup()

return false
})
$(window).bind('scroll resize', function(e){

mainobj.togglecontrol() }) }) } } scrolltotop.init() </script>
