Make sure you just add this, and not the <head>...</head> again. [quote="lukehallppc, post:5, topic:7449"]
<script type="text/javascript"> var clickTag = "http://www.YOUR-URL.com";</script>
[/quote]
Can you try this instead?
<a href="#" onclick="window.open(clickTag)">linked item</a>
If that doesn't work, can you follow the instructions under 'Use a Macro to define the exit URL' and replace the marco with your URL?
