[jQuery] Trouble getting 1 hover to work at a time

[line47]

I know what needs to be done but I'm not sure how to accomplish it.

I want the span inside of the a.appHelpPopup  to show on hover. Right
now both span messages show on hover. :(
I'm not sure how to only get the proper message associated to hover an
not all spans.

Here is my markup.

<script type="text/javascript">
$(document).ready(function() {
$(".checkListMedium .appHelpPopup span").hide();

 $(".checkListMedium .appHelpPopup").hover(
      function () {
      $('.appHelpPopup span').show();  }
,
      function () {
        $(".appHelpPopup span").hide();
      }
    );
});
</script>


-------------

<div class="checkListMedium">
  <label>* Question Type</label>
  <table border="0"
id="applicationForm_AuthoringModeControlsContainer_questionType">
    <tbody>
      <tr>
        <td><input type="radio" language="javascript"
onclick="javascript:setTimeout('__doPostBack(\'applicationForm
$AuthoringModeControlsContainer$questionType$0\',\'\')', 0)"
value="TextBox"
name="applicationForm:AuthoringModeControlsContainer:questionType"
id="applicationForm_AuthoringModeControlsContainer_questionType_0"/>
          <label
for="applicationForm_AuthoringModeControlsContainer_questionType_0">Text
Box<a href="#create" class="appHelpPopup"><img border="0" alt="Text
Box Help" src="help.png"/><span>Provides a box to enter text into.</
span></a></label></td>
      </tr>
      <tr>
        <td><input type="radio" language="javascript"
onclick="javascript:setTimeout('__doPostBack(\'applicationForm
$AuthoringModeControlsContainer$questionType$1\',\'\')', 0)"
value="TextArea"
name="applicationForm:AuthoringModeControlsContainer:questionType"
id="applicationForm_AuthoringModeControlsContainer_questionType_1"/>
          <label
for="applicationForm_AuthoringModeControlsContainer_questionType_1">Text
Area<a href="#create" class="appHelpPopup"><img border="0" alt="Text
Area Help" src="help.png"/><span >Provides an area for entering
multiple lines of text.</span></a></label></td>
      </tr>
    </tbody>
  </table>
</div>



Any help is appreciated thanks!
