Woran stößt sich der IE hier?

[Struppi]

<script type="text/javascript">

var i = 0;
function OpenBoxHeight(box, height, me){
openBoxHeight = window.setInterval("slideHeightOpen('" + box + "', '" + height + "', '" + me + "')", 20);
}

Mach's dir einfacher:
openBoxHeight = window.setInterval(
function() {
slideHeightOpen(box, height , me)
}, 20);
}
