Integrate Worldcat

I need to integrate Worldcat in mij site. I got the directions here posted. I put the <script> in the header file en the code in de page. It doesn t work:

<!– Put in page header –>

<script language=”JavaScript” src=”http://www.worldcat.org/*****.js&#8221; type=”text/javascript”></script>

<!– Put in page body –>

<!– BEGIN worldcat.org search box –>

<div id=”wc_searchbox” style=”display:none;”></div>

<script type=”text/javascript”>

var params = new Object();

params[“source”] = “platform”;

params[“ai”]= “****”;

params[“lang”] = “en”;

params[“host”] = “www.worldcat.org”;

params[“version”] = “1.0”;

// Optional customization, remove if you do not need

/*

params[“title”] = “Find items in libraries near you”; // override branding title

*/

// Call WorldCat to display search box

WCLSearch.display(params, “wc_searchbox”);

</script>

<!– END worldcat.org search box –>

Can you give me directions?
