Object required Message... cannot figure out

I am getting this error:

Message: Object required

Line: 1635

Char: 1

Code: 0

URI: http://www.domainName.whatever/index.cgi?pg=join_ajax

 

End of error...

Line 1635 has this:

 

<input type="text" name="email"  size="45" class="formfield" onblur="joincpf('join_ajax_files','vdd','1','na','email','val',document.getElementById('email').value,'email');" /> <span id="emailimg"></span>

 

Here is the ajax/javascript code:

function joincpf(pag,don,dov,varn1,varn1v,varn2,varn2v,fun) {
request = createRequest();
if(request == null) {
	alert("Unable to Create Request");
	return;
}
var nocache = new Date();
var url = "index.cgi?pg="+pag+"&nw=4&"+don+"="+dov + "&" + varn1 + "=" + varn1v + "&" + varn2 + "=" + varn2v + "&stopIEcache=" + nocache;
if(fun == "fnam") {
	request.open("GET",url,true);
	request.onreadystatechange = fname;
	request.send(null);
} else if(fun == "lnam") {
	request.open("GET",url,true);
	request.onreadystatechange = lname;
	request.send(null);
} else if(fun == "email") {
	request.open("GET",url,true);
	request.onreadystatechange = chkemail;
	request.send(null);
} else {
	request.open("GET",url,true);
	request.onreadystatechange = chkemail;
	request.send(null);
}
}


function fname() {
if(request.readyState == 4) {
	if(request.status == 200) {
		detailDiv = document.getElementById("fnamimg");
			detailDiv.innerHTML = request.responseText;
		}
	}
}
function lname() {
if(request.readyState == 4) {
	if(request.status == 200) {
		detailDiv = document.getElementById("lnamimg");
			detailDiv.innerHTML = request.responseText;
		}
	}
}
function chkemail() {
if(request.readyState == 4) {
	if(request.status == 200) {
		detailDiv = document.getElementById("emailimg");
			detailDiv.innerHTML = request.responseText;
		}
	}
}

 

The script that ajax loads in the back end just prints a line of html, usually an image with some text next to it for example:

 

<img src="/images/data_error.data" border="0"> Field Required!

 

I use ajax on other pages without any errors. Not sure why this one is having any problems. I'd love some feedback. Thank you much,
