Div Class Specific User?

[Inked_Mono]

This one is a little more tricky. I've been looking into ways of creating a dropbox for members to reveal more information, however whenever you hover over a box that isn't the original posters, it just opens up their box anyways.

Example: http://i.imgur.com/mav406k.png

My code (located in Postbit_Legacy):

<center>
<a onmouseover="document.getElementById('div_name').style.display='';" 
onmouseout="document.getElementById('div_name').style.display='none';" 
href="" onclick="return false;" 
style="text-align:center;
text-decoration:none;
padding-left: 31px;
padding-right: 31px;
padding-top: 2px;
padding-bottom: 2px;
background-color: #efefef;
border-top: 1px solid #c4c4c4;
border-right: 1px solid #c4c4c4;
border-left: 1px solid #c4c4c4;
border-bottom: 1px solid #c4c4c4;
margin-bottom: 4px;
margin-top: 4px;">
<b>Member Information</b></a>

<br />

<div id="div_name" style="display:none;
margin:5px 5px 0px 5px;
padding:5px;
border:1px solid #aaa;
position: absolute;
left: 5px;
right: 5px;">

I know it's a little rough around the edges, but does anybody know how I'd be able to make them user specific?
