Getting Error while calling Flex function from JavaScript

Question

Hi,
I have an aspx page, which shows charts as per dropdown selection,
I am using flex charts for flex.In aspx page, i am calling an mxml function using javascript.below is the code for javascript in aspx.
Javascript  code in aspx page:
<script type="text/javascript">     
function callApp(formid) {
    try {
            var objectChart = document.getElementById("statisticsChart");
            alert(objectChart.id);               
            objectChart.myFlexFunction(formid,get('<%=HiddenDashboardWS.ClientID %>').value);
    catch (e) {
        alert(e.message);
function getDropDownListvalue() {
    var IndexValue = $get('<%=FormDropDownList.ClientID %>').selectedIndex;
    var SelectedVal = $get('<%=FormDropDownList.ClientID %>').options[IndexValue].value;
    //  alert(SelectedVal);
    callApp(SelectedVal);
</script>
Html code where dropdown control is placed
<asp:DropDownList CssClass="combo" ID="FormDropDownList" runat="server" AutoPostBack="false"></asp:DropDownList>
<object id="statisticsChart" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,0,0"
height="220" width="680">
    <param name="src" value="../swf/DashboardStatisticChart.swf" />
    <param name="flashVars" value="" />
    <embed name="statisticsChart" src="../swf/DashboardStatisticChart.swf" pluginspage="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" height="220" width="680" flashvars=""></embed>
</object>
Mxml code:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"  backgroundColor="white" creationComplete="initApp();" >
<mx:script>
  public function initApp():void {
ExternalInterface.addCallback("myFlexFunction",myFunc);
  public function myFunc(s:String,wsurl:String):void {
     Formid.text = s;
     webService.wsdl = wsurl;
     Alert.show("webservice");
//Getdata calls webservice and gets xml data    
GetData();
//showchart() will draw chart
                 ShowChart();
</mx:script>
</mx:Application>
Above code works perfect in ie, but in firefox, it gives An error saying “chartObject.MyFlexFunction is not a function”.
I am getting the object in javascript in all the browsers, but not the functions!
Does anyone has worked with this?
Any help will be highly appreciated.
