Jquery code not working in IE 9 but works in FF and Chrome
<p>I have this JQuery to show/hide rows that is not working in IE9 and it is extremely time sensitive and I have absolutely no idea how to fix it. I tried adding a meta tag for IE8 which made it work but completely messed up the formatting. I am unsure of its native functionality in IE8. It does function in Firefox and Chrome.</p>

<pre><code>function showNext(opt)  {       
      takeAway();     

      var optMap={
             "Picked Up":"#pickedup",
             "Bus to alternate":"#altad2,#altad1",
             "Walk to alternate":"#altad2,#altad1",
              };
           $(optMap[opt]).css("display","") ;       

}
</code></pre>

<p>The function is called here</p>

<pre><code>&lt;tr class="~[evenoddrow]"&gt; 
        &lt;td class="bold"&gt;In the event of early dismissal I would like my child to:&lt;/td&gt;&lt;td id="Emergclose_Action"&gt;~([01]Emergclose_Action)&lt;/td&gt;&lt;td class="gwCen"&gt;&lt;/td&gt;
        &lt;td&gt;&lt;select name="eReg|Emergclose_Action" id="eReg|Emergclose_Action" onChange="showNext(value);"&gt;
                &lt;option&gt;&lt;/option&gt;&lt;option value="Walk home as normal"&gt;Walk home as normal&lt;/option&gt;&lt;option value="Ride the bus as normal"&gt;Ride the bus as normal&lt;/option&gt;
&lt;option value="Picked Up"&gt;Be picked up immediately after dismissal&lt;/option&gt;&lt;option value="Bus to alternate"&gt;Ride the bus to an alternate address&lt;/option&gt;&lt;option value="Walk to alternate"&gt;Walk to an alternate address&lt;/option&gt;
            &lt;/select&gt;           
        &lt;/td&gt;
    &lt;/tr&gt;
</code></pre>

<p>The displayed rows are below </p>

<pre><code>&lt;tr class="~[evenoddrow]" id="pickedup" style="display:none;"&gt; 
&lt;td class="bold"&gt;Name of the person that will be picking up your child:&lt;/td&gt;&lt;td id="Emergclose_Who_Pickup"&gt;~([01]Emergclose_Who_Pickup)&lt;/td&gt;&lt;td class="gwCen"&gt;&lt;/td&gt;
        &lt;td&gt;&lt;input type="text" name="eReg|Emergclose_Who_Pickup" id="eReg|Emergclose_Who_Pickup" value="" size="30" /&gt;&lt;span class="gwExample"&gt;last,&amp;nbsp; first&lt;/span&gt;&lt;/td&gt;
    &lt;/tr&gt;
&lt;tr class="~[evenoddrow]"  id="altad1" style="display:none;"&gt; 
        &lt;td class="bold"&gt;&lt;span style="padding: 0 25px"&gt;I would like my child to go to the home of:&lt;/td&gt;&lt;/span&gt;&lt;td id="Emergclose_Alt_Name"&gt;~([01]Emergclose_Alt_Name)&lt;/td&gt;&lt;td class="gwCen"&gt;&lt;/td&gt;
