[RESOLVED] Ajax & Firefox problem

So I want a form that is submitted with ajax. What I have so far works fine in IE but not in Firefox. Heres my code:

Code:

---

//Sends Sign-Up Form
function sendsuf(){
        var ajaxRequest;
       
        try{
                // Opera 8.0+, Firefox, Safari
                ajaxRequest = new XMLHttpRequest();
        } catch (e){
                // Internet Explorer Browsers
                try{
                        ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
                } catch (e) {
                        try{
                                ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
                        } catch (e){
                                // Something went wrong
                                alert("Your browser broke!");
                                return false;
                        }
                }
        }
        // function that will receive data sent from the server
        ajaxRequest.onreadystatechange = function(){
                if(ajaxRequest.readyState == 4){
                                alert(ajaxRequest.responseText);
                }
        }


//  I think the problem is somewhere below this line

        ajaxRequest.open('POST', 'adduser.php', true);
        ajaxRequest.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
        ajaxRequest.setRequestHeader("Content-length", params.length);
        ajaxRequest.setRequestHeader("Connection", "close");

            var fullname = document.getElementById('fullname').value;
            var email = document.getElementById('email').value;


        ajaxRequest.send('fullname=' + fullname + '&email=' + email);
}

Any ideas?

Thanks

OK so the point is... Don't give you form elements the "name=" parameter instead of "id=" when you're trying to retrieve their id. I'm not sure why that stopped anything from going through, but it did.
