Javascript windows.open error
<p>I have the following code at the end of my page.  </p>

<pre><code>&lt;script&gt;
$(".btn_fb").click(function() {
    window.open("http://www.facebook.com/sharer.php?u="+document.URL+"&amp;amp;t=&lt;%hdl_Title%&gt;", "Facebook", "width=660,height=400,scrollbars=no;resizable=no");
    return false;
});    
$(".btn_tw").click(function() {
    window.open("http://twitter.com/home?status=&lt;%hdl_Title%&gt; "+document.URL+"", "Twitter", "width=660,height=400,scrollbars=no;resizable=no");
    return false;
});    
$(".btn_li").click(function() {
    window.open("http://www.linkedin.com/shareArticle?mini=true&amp;amp;url="+document.URL+"&amp;amp;title=&lt;%hdl_Title%&gt;;summary=&lt;%hdl_Title%&gt;", "LinkedIn", "width=660,height=400,scrollbars=no;resizable=no");
    return false;
}); 

$('.btn_go').click(function() {
    window.open("http://plus.google.com/share?url="+document.URL, 'Google Plus', 'width=660,height=500,scrollbars=no;resizable=no');
    return false;
});     
$(".btn_ma").attr("href", "mailto:?subject=&lt;%hdl_Title%&gt;&amp;body=Hi%0D%0A%0D%0AI thought you may be interested in this: &lt;%hdl_Title%&gt; " + window.location); 
</code></pre>

<p></p>

<p>IE9 throws an error when it hits this part of the script and I cannot pin point what the error is. FF doesn't throw an error. </p>

<pre><code>&lt;script&gt;   
    $('.button_google_plus').click(function() {
        window.open("http://plus.google.com/share?url="+document.URL, 'Google Plus', 'width=660,height=500,scrollbars=no;resizable=no');
        return false;
    }); 
&lt;/script&gt; 
</code></pre>

<p>NB: the code: </p>

<pre><code>&lt;%hdl_Title%&gt;
</code></pre>

<p>is a parameter set in the CMS. </p>
