Jquery Chained Select Not working in IE7
<p>I currently have been playing around with jquery.chained.js and have it working in FF, IE8+, Safari, Chrome... The issue is that in IE7 it shows all values no matter what option is selected. Here is my code.</p>

<pre><code>  &lt;script type="text/javascript" charset="utf-8"&gt;  
  $(function() {

/* For jquery.chained.js */
$("#year").chained("#make");
$("#model").chained("#year");

$("#button").attr("disabled", true);
$("#model").bind("change", function(event) {
    if ("" != $("option:selected", this).val() &amp;&amp; "" != $("option:selected", $("#model")).val()) {
      $("#button").attr("disabled", false);
    } else {
        $("#button").attr("disabled", true);          
    }
});
</code></pre>

<p>});
   </p>

<pre><code> &lt;select style="width:125px" name="make" id="make"&gt;
      &lt;option value=""&gt;Make&lt;/option&gt;
      &lt;option value="Ford"&gt;Ford&lt;/option&gt;
      &lt;option value="GM"&gt;GM&lt;/option&gt;
      &lt;option value="Other"&gt;Other&lt;/option&gt;
    &lt;/select&gt;
    &lt;select style="width:125px" name="year" id="year"&gt;
      &lt;option value=""&gt;Year&lt;/option&gt;

      &lt;option value="FordYear1" class="Ford"&gt;Ford Year Range 1&lt;/option&gt;
      &lt;option value="FordYear2" class="Ford"&gt;Ford Year Range 2&lt;/option&gt;
      &lt;option value="FordYear3" class="Ford"&gt;Ford Year Range 3&lt;/option&gt;


      &lt;option value="1991-1992" class="GM"&gt;1991-1992&lt;/option&gt;
