I got error message in Firefox when passing the dropdown value to the next page

Question

Hello:
I am using Ajax to populate a dropdown box. When I pass the
value to the next page, I got an error message saying
'form.thevalue' is undefined in Firefox. It works fine in IE.
Please find part of the code below:
form.cfm:
<select name="appointment_date" id="appointment_date"
onchange="showTime(document.apptform.select_employee.value,
this.value, ' ' )">
<option value=''>[Select]</option>
<cfloop list="#datelist#" index="thedate">
<cfif thedate eq '#chg_appointment_date#'>
<cfset select='SELECTED'>
<cfelse>
<cfset select=''>
</cfif>
<cfoutput><option value="#thedate#"
#select#>#thedate#</option></cfoutput>
</cfloop>
</select>
<span id="TimeList"></span>
GetTime.js:
var oXmlHttp
function showTime(staff, date, available)
var url="/cf/misc/GetTime.cfm?nicknm=" + staff + "&dt=" +
date + "&ti=" + available
oXmlHttp=GetHttpObject(stateChanged)
oXmlHttp.open("GET", url , true)
oXmlHttp.send(null)
function stateChanged()
if (oXmlHttp.readyState==4 ||
oXmlHttp.readyState=="complete")
document.getElementById("TimeList").innerHTML=oXmlHttp.responseText
function GetHttpObject(handler)
try
var oRequester = new XMLHttpRequest();
oRequester.onload=handler
oRequester.onerror=handler
return oRequester
catch (error)
try
var oRequester = new ActiveXObject("Microsoft.XMLHTTP");
oRequester.onreadystatechange=handler
return oRequester
catch (error)
return false;
GetTime.cfm:
<CFINCLUDE TEMPLATE="include.cfm">
<cfset timelist = arrayToList(structSort(atime,
"numeric"))>
<span>
<select name="available_time">
<cfif #trim(URL.nicknm)# eq 'All'>
<option value=''>[Select]</option>
<cfloop list='#timelist#' index='time'>
<cfif time EQ '#trim(url.ti)#'>
<cfset select = 'SELECTED'>
<cfelse>
<cfset select = ''>
</cfif>
<cfoutput><option value="#atime[time]#"
#select#>#time#</option></cfoutput>
</cfloop>
<cfelse>
</cfif>
</select>
</span>
When I pass #form.available_time# to the next page, in
Firefox I got error saying 'form.available_time' is undefined. Any
idea, please?
Thanks in advance.
