Need help with script with window.open, script works in seamonkey but not in IE 8

[Terranbeastsam]

I have a script that works in seamonkey(my html editor) but when I use it in IE8 it says errors happen.
Here's the code (the first line is on line 7 of the html file):

<script type="text/javascript">
function enlarge(imageNum)
{
var numToString = "";
if(parseInt(imageNum) < 10){
numToString = "0" + imageNum;
}
else
{
numToString = imageNum + "";
}
window.open("images/LgScreenshot"+numToString+".jpg","Screenshot "+imageNum,"status=0,height=675,width=900,resizable=0");
}
</script>

And the errors:

I don't think IE likes the space in the window name.

[Terranbeastsam]

the space isn't the problem, i removed it and it is still not working, just new errors. If you need the entire html code I can give it to you

I think your runslideshow() is undefined.
