1) Taka út allt sem hefur með core, jquery og ui.tabs að gera.

2) Bæta inn notkun á rdn.js og rdnCurtains.js:

	<script src="rdn.js" type="text/javascript"></script>
	<script src="rdnCurtains.js" type="text/javascript"></script>

3) Linkarnir eiga að vera svona:

	<a id="basketLink" href="javascript:TogglePanel('basketContainer','basket');">

4) Panelarnir eiga að vera svona (bæta id="basket" við basket-ið...):

        <div id="basketContainer">
		<div id="basket" class="basket">
