Mouseover java issues on IE8 only

I have a few java events attached to a couple rollover buttons. They seem to all work just great on every browser but ie8 for some reason.

<script type="text/javascript"src=“lookbook_web/mouseovers.js”>

[SIZE=2]<div id=“thumb_container”>
<div id=“thumb1”><a href="javascript:void()"onmouseover="ShowPage(‘frame1’)"onclick=“ShowPage(‘frame1’)” target=“mainbox”></a></div>
<div id=“thumb2”><a href="javascript:void()"onmouseover="ShowPage(‘frame2’)"onclick=“ShowPage(‘frame2’)” target=“mainbox”></a></div>
<div id=“thumb3”><a href="javascript:void()"onmouseover="ShowPage(‘frame3’)"onclick=“ShowPage(‘frame3’)” target=“mainbox”></a></div> [/SIZE]

And then the mouseovers.js file looks like this (this is just a script i found online and edited so my guess is that the issue is here):
[COLOR=#000000][FONT=Times]
function ShowPage(frame1)
//Display in the i-frame, the page whose name is aName
{
{
frames[0].location = frame1+’.html’
}

function ShowPage(frame2)
//Display in the i-frame, the page whose name is aName

{
frames[0].location = frame2+’.html’
}

function ShowPage(frame3)
//Display in the i-frame, the page whose name is aName

{
frames[0].location = frame3+’.html’
}
}

Like i said, works on ffox, safari, ie7, chrome… so im sort of at a loss. Ideas?
