Answered OnChange event Javascript to call web service

    I have a checkbox on a form.  When this checkbox is clicked I need it to trigger a webservice.  I am still new to SOAP so please let me know is I am doing anything wrong.  The error I'm getting is "The value of the property 'startService' is null or undefined, not a Function object"  What does that mean?

    Here is the javascript I'm using:

    function startService(name)
    {
    var xml = "<?xml version='1.0' encoding='utf-8'?>" +
    "<soap:Envelope xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/' "+
    " xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' " +
    " xmlns:xsd='http://www.w3.org/2001/XMLSchema'>"+
    "<soap:Body>" +
    "<createrole xmlns=\'http://tempuri.org/\'>" +
    "<name>" + name + "</name>" +
    "</createrole>" +
    "</soap:Body></soap:Envelope>";

    xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
    xmlHttp.open("POST","http://localhost/CreateRoles/Service1.asmx?wsdl", true);
    xmlHttp.setRequestHeader("Content-Type","text/xml; charset=utf-8?);
    xmlHttp.setRequestHeader("Content-Length",xml.length);

    xmlHttp.send(xml);
    }

    I tested to see is "Name" was being passed in properly by changing the code to "alert("hello" + name);" and it worked perfectly.  and I kept the function name as startService for the alert change as well.  So I know the problem is in the code somewhere.  All help is greatly appreciated.

    "<createrole xmlns=\'http://tempuri.org/\'>" +

    I think using the \ before the ' causes it to escape, this might be one issue.

         xmlHttp.setRequestHeader("Content-Type","text/xml; charset=utf-8?);

    The other is that you're missing a matching ["] in this line.

    Hi

    you create following function on load of form

    function myFuction()
     {
        crmForm.all.checkboxfieldname.onclick = function () {

         crmForm.all.checkboxfieldname.FireOnChange();

        };
    }

    then your function on checkbox onChange

    function startService(name)
    {

    }
