Problem with variable transfer...

[BillyBoB6969]

I am trying to make an image (the edit img) appear when the user logs in. It has a function for the onmousedown event that should transfer the variable from ajax xmlresponse to the img attribute pID.

function editBlog(EntryID, SecurityCode) {
	alert(EntryID);
}

function makeEditable(userID) {
	if(sendReq2.readyState == 4 || sendReq2.readyState == 0) {
		sendReq2.open("POST",'includes/getPosts.php?userID='+userID+'&secCode='+secCode, true);
		sendReq2.onreadystatechange = function() {
			if(sendReq2.readyState == 4) {
				var xmlDoc = sendReq2.responseXML.documentElement;
				var i = 0;
				var items = xmlDoc.getElementsByTagName("entry");
				var o = [];
				var iEdit = [];
				var iRemove = [];
				while(i<items.length) {
					iEdit[i] = document.createElement("img");
					iEdit[i].pID = items[i].attributes[0].textContent;
					iEdit[i].src = "images/EditBtn.jpg";
					iEdit[i].alt = "Edit";
					iEdit[i].onmousedown = function() {
						editBlog(this.pID, secCode);
					}
					iRemove[i] = document.createElement("img");
					iRemove[i].src = "images/RemoveBtn.jpg";
					iRemove[i].alt = "Remove";
					var posID = items[i].firstChild.textContent;
					o[i] = document.getElementById('BlogO'+posID);
					clearObj(o[i]);
					o[i].appendChild(iEdit[i]);
					o[i].appendChild(document.createTextNode(" "));
					o[i].appendChild(iRemove[i]);
					i++;
				}
			}
		}
		sendReq2.send(null);
	}
}

It just outcomes undefined... The url to the site is: The Site.

I reloaded the page and got it to work. Thanks for looking anyways.
