Displaying The Fetched Data From Db On MouseOver In A Table

I have a code that will fetch out the data from database OnMouseOver. But it is working fine if don't add table on the div which will come OnMouseOver. If i try to show the fetched data in table then the code doesn't work. Here is my code:

<script type="text/javascript" language="JavaScript">
var cX = 0; var cY = 0; var rX = 0; var rY = 0;
function UpdateCursorPosition(e){ cX = e.pageX; cY = e.pageY;}
function UpdateCursorPositionDocAll(e){ cX = event.clientX; cY = event.clientY;}
if(document.all) { document.onmousemove = UpdateCursorPositionDocAll; }
else { document.onmousemove = UpdateCursorPosition; }
[Code]....
