Try making 'animatedcollapse.js' this:


//Animated Collapsible DIV- Author: Dynamic Drive (http://www.dynamicdrive.com)
//Last updated Aug 1st, 07'. Fixed bug with "block" parameter not working when persist is enabled
//Updated June 27th, 07'. Added ability for a DIV to be initially expanded.

var uniquepageid=window.location.href.replace("http://"+window.location.hostname, "").replace(/^\//, "") //get current page path and name, used to uniquely identify this page for persistence feature

function animatedcollapse(divId, animatetime, persistexpand, initstate){
this.divId=divId
this.divObj=document.getElementById(divId)
this.divObj.style.overflow="hidden"
this.timelength=animatetime
this.initstate=(typeof initstate!="undefined" && initstate=="block")? "block" : "contract"
this.isExpanded=animatedcollapse.getCookie(uniquepageid+"-"+divId) //"yes" or "no", based on cookie value
this.contentwidth=parseInt(this.divObj.style.width)
var thisobj=this
if (isNaN(this.contentwidth)){ //if no CSS "width" attribute explicitly defined, get DIV's width on window.load
animatedcollapse.dotask(window, function(){thisobj._getwidth(persistexpand)}, "load")
if (!persistexpand && this.initstate=="contract" || persistexpand && this.isExpanded!="yes" && this.isExpanded!="") //Hide DIV (unless div should be expanded by default, OR persistence is enabled and this DIV should be expanded)
this.divObj.style.visibility="hidden" //hide content (versus collapse) until we can get its width
}
else if (!persistexpand && this.initstate=="contract" || persistexpand && this.isExpanded!="yes" && this.isExpanded!="") //Hide DIV (unless div should be expanded by default, OR persistence is enabled and this DIV should be expanded)
this.divObj.style.width=0 //just collapse content if CSS "width" attribute available
if (persistexpand)
animatedcollapse.dotask(window, function(){animatedcollapse.setCookie(uniquepageid+"-"+thisobj.divId, thisobj.isExpanded)}, "unload")
}

animatedcollapse.prototype._getwidth=function(persistexpand){
this.contentwidth=this.divObj.offsetwidth
if (!persistexpand && this.initstate=="contract" || persistexpand && this.isExpanded!="yes"){ //Hide DIV (unless div should be expanded by default, OR persistence is enabled and this DIV should be expanded)
this.divObj.style.width=0 //collapse content
this.divObj.style.visibility="visible"
}
else //else if persistence is enabled AND this content should be expanded, define its CSS width value so slideup() has something to work with
this.divObj.style.width=this.contentwidth+"px"
}


animatedcollapse.prototype._slideengine=function(direction){
var elapsed=new Date().getTime()-this.startTime //get time animation has run
var thisobj=this
if (elapsed<this.timelength){ //if time run is less than specified length
var distancepercent=(direction=="down")? animatedcollapse.curveincrement(elapsed/this.timelength) : 1-animatedcollapse.curveincrement(elapsed/this.timelength)
this.divObj.style.width=distancepercent * this.contentwidth +"px"
this.runtimer=setTimeout(function(){thisobj._slideengine(direction)}, 10)
}
else{ //if animation finished
this.divObj.style.width=(direction=="down")? this.contentwidth+"px" : 0
this.isExpanded=(direction=="down")? "yes" : "no" //remember whether content is expanded or not
this.runtimer=null
}
}


animatedcollapse.prototype.slidedown=function(){
if (typeof this.runtimer=="undefined" || this.runtimer==null){ //if animation isn't already running or has stopped running
if (isNaN(this.contentwidth)) //if content width not available yet (until window.onload)
alert("Please wait until document has fully loaded then click again")
else if (parseInt(this.divObj.style.width)==0){ //if content is collapsed
this.startTime=new Date().getTime() //Set animation start time
this._slideengine("down")
}
}
}

animatedcollapse.prototype.slideup=function(){
if (typeof this.runtimer=="undefined" || this.runtimer==null){ //if animation isn't already running or has stopped running
if (isNaN(this.contentwidth)) //if content width not available yet (until window.onload)
alert("Please wait until document has fully loaded then click again")
else if (parseInt(this.divObj.style.width)==this.contentwidth){ //if content is expanded
this.startTime=new Date().getTime()
this._slideengine("up")
}
}
}

animatedcollapse.prototype.slideit=function(){
if (isNaN(this.contentwidth)) //if content width not available yet (until window.onload)
alert("Please wait until document has fully loaded then click again")
else if (parseInt(this.divObj.style.width)==0)
this.slidedown()
else if (parseInt(this.divObj.style.width)==this.contentwidth)
this.slideup()
}

// -------------------------------------------------------------------
// A few utility functions below:
// -------------------------------------------------------------------

animatedcollapse.curveincrement=function(percent){
return (1-Math.cos(percent*Math.PI)) / 2 //return cos curve based value from a percentage input
}


animatedcollapse.dotask=function(target, functionref, tasktype){ //assign a function to execute to an event handler (ie: onunload)
var tasktype=(window.addEventListener)? tasktype : "on"+tasktype

target.addEventListener(tasktype, functionref, false)

animatedcollapse.getCookie=function(Name){
var re=new RegExp(Name+"=[^;]+", "i"); //construct RE to search for target name/value pair
if (document.cookie.match(re)) //if cookie found
return document.cookie.match(re)[0].split("=")[1] //return its value
return ""
}

animatedcollapse.setCookie=function(name, value){
document.cookie = name+"="+value
}
